Greetings,

I've been a long time BMW fanatic and have been looking into getting a Porsche for daily driver duties. This specific example was a dealer demo for the first three thousand miles of its life so that left me a bit weary about engine wear and if it was properly broken in. The owner afterward took great care of the car, owned it for a little under 8 years. The interior and exterior look immaculate and there is a handful of documentation, that of which I still need to go over. It's a fully loaded car, save for the Sport steering wheel. PASM, Sport Chrono, Navi, etc

The mileage is the highest I've seen and it worries me a bit, only because it's a Porsche. My first E46 M3 had a tad over 150K and with consistent maintenance, ran as strong as day 1. Doing my share of research I see the first gen engines are rather dispensable if tracked, although I don't see myself tracking the car so that shouldn't be an issue. The car is an automatic, which I'm OK with since it'll be my DD so that leaves overrevs out of the equation. I'm a fairly decent mechanic and will be putting the car on a lift for inspection. Is there anything else I should look out for? or should I run for the hills on a car with this kind of mileage....?

Cheers

p.s. I would love to do a oil analysis to see what kind of shape the IMS is in but I do not think that is an option with this seller...

Welcome.
Does the current owner have maintenance records? How often was the oil changed? That would be the item to zone in on. If the interval was more than 8K, you might want to keep looking. 5-8K is the generally accepted interval for oil changes. Also, at that mileage, you may have suspension bushings that have seen better days. Check to see if it tracks straight.

You may be asking the wrong group this question as there will be garage queen owners who will blanch at mileage this high and tell you find something else. Just go into the transaction with eyes wide open. Since you've owned a BMW, you know German parts are expensive. With mileage that high and the age of the car, there will be parts that will need replacing. Tips don't hold their value as well as 6spds, so with the mileage and Tip, hopefully you're looking at a price somewhere around $20K.

I'm not aware of guys with ultra high mileage on this forum, but there's a guy in your neck of the woods who's on the Boxster forum and he has 260K miles on his 986. I had to chuckle about your statement that you're worried about the first 3K mi of this 129K mi car.

Good luck with your decision.

If it looks good and feels good, it probably is good - and the price ought to be very good.

Looks great! A good price would be about $15.5K. I'm glad to see some 987s with high mileage in such good shape. I'd like to keep my 08 CS until it has 150K miles. As my DD I have 46K miles but my commute will go from 5 miles per day to 65 miles per day. The only good thing about the long commute is I'll be in my CS the whole way and when I get home, I can walk out of my back door on to the 1st hole of the golf course.

Are there any others with high mileage out there? I'd love to hear their thoughts. Rob

I purchased my 06 in February 2013 with 138k miles on it. It appeared to have only one real owner prior to me since new so it was probably their daily driver with that kind of mileage on it. In May 2013 at 145k miles while doing a brake service my dad noticed an odd noise in the engine. Upon further investigation it was determined that the IMS bearing was failing and we caught it just in time. Every weekend that summer I could make the 3 hour drive home were spent doing an engine rebuild.

I'm not telling you this to scare you; I think you should be aware that eventually component(s) wear out, some necessitating full tear down and rebuild. Ironically most everything else in the engine was pretty good: compression, leakdown, crank thrust, etc.

Given your year, mileage, and options, I would pay no more than high teens for that car. Good luck.

There seems to be expectations of 100% non wear out versus 1% failure of the infamous IMS. Make sure the price is correct and just have your eyes wide open. The 2006 are great cars and have a great following for that reason above all others. But 100% of the IMS are going to wear out eventually. I'd do the oil analysis to check the rod brg condition. If you had a dealer do it they can check for over revs

You may want to check / ask about oil consumption.

Plan on a new water pump, depending on when it was last replaced. Look for coolant leaks, as the coolant tank and some other plumbing bits are plastic.

And listen for a whining/grinding power steering pump - another weak spot. The driver's side intake manifold has to come off and the A/C compressor moved to get it out. Book labor time is about 10 hours for that ... And the pump is at least $430 ... You could drop $2K replacing it and they can be a weak link.

Listen for it, it's right behind the driver's head. I replaced mine myself when I had more time than money, off and on it took 3 days and was a pain.

You may want to pick up Wayne Dempsey's (he of pelicanparts.com) book 101 projects for your Porsche boxster -- it's more 986 focused but notes differences with 987s, and covers many aspects of the car. Covers maintenance, upgrades ... An excellent resource.

It really is a simple car. I'll be turning 100k miles in a few weeks in mine.

Everyone - the insight, advice and knowledge you've provided me was extremely helpful, thank you! I checked the thread this morning and could not believe the amount of response I got, I went into the deal well armed. Luckily for me the car checked out, no awkward noises from the power steering or water pump, suspension was clean and all bushings intact, no unusual tire wear to indicate worn components, rotors are straight and not scored, minor seepage from the engine but nothing to be alarmed about (especially with this kind of mileage). Aesthetically the car looks like it has no more than 60K, the interior and exterior were definitely well kept, front bumper looks like it was resprayed at one point, most likely from rock chips given the mileage is all freeway.

Welcome.

Thank you! so the seller had a handful of records, not as much as I'd like but paying specific attention to the oil changes, they were right around where you said they should be, some even before 5K. The price was less than $20K. I actually ended up walking away from the sale only to talk myself into it a quarter of the way home. I made him an offer, he accepted and I turned around to close the deal.

If it looks good and feels good, it probably is good - and the price ought to be very good.
Check, check and check!

15.5K would of been a steal! I paid a tad higher but I'm OK with it :) happy golfing!

Duly noted! I watched a few YouTube videos of failing IMS bearings and got an idea of what they sounded like. I put the car on a lift with the engine running and to my surprise, no unusual noises, pretty quiet actually!

It's a tiptronic so over revs are out of the question, I plan on sending an oil sample to Blackstone on the next change.

I will definitely be checking out that service manual, thanks for the reference. As for a water pump replacement, I could not find one in the maintenance records so will plan on doing that eventually.

My research shows that the all M96/M97 engines manufactured from 06-08 have a non-serviceable large single row bearing. Am I mistaken?

was your M3 an AT?

honestly - i would look for an MT - but that's just me typing.
Since this Cayman will be used for daily driving duties I didn't mind an AT, I'll be using it to scoot around while I offload some of my other cars. As for the M3, I've had a few actually, both SMG and 6MT. My current one, which is on the market btw, is a HPF Stage 1 making 623RWHP at 13psi :) she is a 6MT.

Congrats on your "new" Cayman! Sounds like it should fit your mission statement well. And it looks great on those 19" Carrera Classics. My favorite among the factory 987 wheels. Then there's the nutty E46! Thanks for sharing the pics/info. Absolutely love them and actually shopped hard for one before deciding to go with two seats. I was going to pay a premium for one of Enthusiast Auto Groups' cars. My exchanges with them were great and their selection is over the top. I still plan to own one someday and they'll be the first people I check in with.

Wishing you many happy smiles!

Congrats on the car! I'm also a new to Caymans. Is that the one that was in Santa Cruz?

Thank you good sir!

Thanks and yep, that would be the one.

Congrats on the purchase.

High mileage cars with proper maintenance history are nothing to be scared of. Nothing. It humors me every time I see a quivering planet-9 user balk at the idea of a high mileage CS. In retrospect, I would have purchased a higher mileage CS and saved a pile of cash. Great car.

As far as this E46. Please link me to the for sale ad.

Congrats. Love the BMW. May I ask why you decided to go with a Cayman instead? It looks like a lot of work/money went into the BMW.

My thoughts exactly, being mechanically inclined and able to do your own maintenance/repairs comes in handy also. Here is the FS thread on M3Forum - FS: 2002 M3 Alpine White / Imola / Slicktop / 6MT / HPF Stage 1 600RWHP E85 Sleeper - BMW M3 Forum.com (E30 M3 | E36 M3 | E46 M3 | E92 M3 | F80/X)

I love bimmers, especially the E46 platform but I'm at a point in my life where I need to step away from the car scene for a bit and focus on other priorities. In search of a a car that overall delivers led me to the Cayman, the rest is history.
