Hello folks,

I've been thinking a lot lately about whether I should sell my 2005 Boxster S. I got it new back in May, 2005 and have loved every minute with the car. It's still in great condition, but it now has 147,000 miles on it. Still on the original motor. Still on the original clutch, if you can believe that. One could say I've been gentle with the car. My prior experience in the DSM world may have also taught me a lot about how to baby a car though, HAH!

But 147,000 seems pretty high mileage for a Boxster when I see how many low mileage ones there are on the market. I'm also worried that if I were to blow the engine at this point, the replacement might be more than the value of the car. So I've been considering options.

Obviously, buying a new 718 or a near-new 981S is an option. These cars have gone crazy in price however. I got mine for $62,000 back in 2005 with PASM, Sport Chrono, PCM, xenons, and a few other small options. Something similarly spec'd these days is around $80k. That's way more than inflation, and I can think of a LOT of other things I'd rather do with $80k (a used 360 Modena comes to mind...).

For $46k though, you can get a pretty good 2013 981S. For $27k, you can get a nice, low-mileage 987.2 S. Edmunds is telling me that mine is worth around $15,000 private party. Blowing up the engine could be a huge loss.

What do you think? This car and I have been through a lot together, and I'm really fond of it. Still worth keeping, or is it time to trade up?

I don't think you would get $15k for your car but might as well try!
I'm not as concerned with the specific value of my car, more so about whether or not it's worth keeping versus selling, you see. Is it worth it to risk the danger of the motor going out on me? Knowing how much a motor replacement costs on these, it seems that maybe a modern Porsche isn't a "keep it forever" sort of car.

If you are worried about the engine get a 3.8 purpose built for your car and keep it for another 12 years. You can get a lot of motor for less than a newer car. You won't get 15k for a high miler boxster. Check out the online market.

Hard to tell on motor... Nobody has that history like commuter cars.. But as other poster said motor is cheaper than new car.

What are you looking for (faster? handle better?)to replace it? I've had my Boxster S for 17 years, and while it has had a couple garage mates over that time, I've never seen anything I want to replace it. And the values are low enough now, I can afford to leave the residual value in it. 147,000 miles? Who says that's high? Anecdotally, the low mile cars have more IMS issues. Check the maintenance costs before picking up that 360 Modena! ;)

The time to trade up was probably in 2010. Just relax and enjoy it.

Just browsing eBay I see the same year car with 84k asking $14K. As for blowing an engine I see lots of 3.2L Boxster engines in the $4-5K range with less then half the miles of your car, figure another $2-2.5K for installation and you would be looking at $6-7K for an engine replacement, about half what KBB says the car is worth. On the other hand, these are tough engines and you might get another 100K out of it and not every engine is unrepairable, I mean do Porsche engine's just blow or something? Anyway, if you want a newer/nicer BS go for it and get a 981, you will love it.

The time to have asked this question was 70K mi ago. Once Porsches click into 6 digits on mileage, the value plummets. The price guides are designed for normal cars like Camrys and Accords and for people who have no qualms about running cars into the 200K mi range. But Porsche buyers are different - they're looking for cars in the 20-50K mi range. There is an 05 Boxster S w/ 125K mi for $16K that's been for sale in KC for over a yr. At this point, your car is worth the value of a roller ($3500) plus the value of a running engine.

Your car is capable of many more miles. There's a guy on 986forum who lives in the SF area and has 290K mi on his 986 Boxster. With proper maintenance, these cars can go for lots of miles.

If you plan to pack lots of miles on your Porsches, you may want to buy one that's 4 yrs old with 20-25K mi. I suggest 4 yrs old b/c that's when the first major depreciation occurs (not counting when you drive it off the lot) due to warranty running out. Drive it up to 88K mi and get rid of it. That way you're buying at a low point and selling before a major low point. Rinse and repeat.

Thank you for all the advice, folks. Yeah I held onto this one far too long, clearly. I never had a plan for it. The only thought I had was along the lines of, "Well I already have a Boxster, why would I want to buy another one?"

It was my daily driver up until around 2013, and now I'm not really putting many miles on it. So I suppose that even if the engine only lasts me 20,000 more miles, that would still be another five years or so at least. If there really is not that much residual value left, I might as well just "drive it till it breaks". I actually find that thought rather satisfying. If it ends up actually making it to 200,000 miles or so, so much the better. I've been very surprised by the car's durability over the years.

Of course, I brought the topic up with a friend of mine last night and he's now all excited about swapping in a 3.8L with me in my garage. That is apparently not a very practical thought on a non-DFI car from my quick googling, but hey, who knows. :)

Again, thanks for the opinions!

You could probably do the IMS, water pump and clutch altogether if needed, and get another 75-100k out of it without spending a ton of money. Probably you could do that for what you would spend in sales tax on the next one. If you enjoy the car, do the maintenance before you essentially total it.

Yeah I've kept up with all maintenance on the car, and I doubled the oil change intervals straight out the gate from 20,000 miles to 10,000 miles. The IMS was changed a couple years ago when it started whistling and the dealership told me "don't drive it here, tow it here!" At that time, we discovered that the existing clutch still had 50% life on it...after 140,000 miles. I was shocked. I had told them to replace the clutch while they had everything apart but when they told me that, I just had them slap it all back together.

Next up, the CV boots are leaking and my bump stops have disintegrated. But water pump does seems like something that needs doing soon too, I'll have to check out the service schedule.

I am convinced. The car gets to stick around! The wife isn't too amused with my car hoarding but she's getting used to it and she prefers this idea to the thought of spending more on another one. :)

Maybe I'll get new wheels finally.

That's good, but water pump could still be an issue. An acquaintance who runs a local independent Porsche service shop here has seen engine failures caused by failure of water pump impellers which are plastic. Gradual overheating as vanes fail cause pumping to become less efficient. This caused heads to crack. He said this failure in older Boxsters totals the engine. My recollection is some will start to leak at this point, and some don't. You might want to do some research on this. 911'S of that vintage have also been reported to have the problem. One thread on the subject says LN Engineering recommends replacement with a new OEM water pump every 4 years. It seems worth a little current research.

Yeah, I can't think of any car that likes it when the water pump dies, I'm used to replacing them early. Thanks for the advice though. I've only recently had cars that weren't daily drivers, and I'm starting to have to think about maintenance differently than before. Can't just do things on mileage intervals, now I have to think about how long it's been since something was done.

Your engine will easily last past 200k. If you like your car, keep it.

As someone who knows the market, sell it. Move into a 981. Now is the right time. If you can get 15k out of your car that would be fantastic--but I'd prepare fore 10-12k. Go drive a 981 and you will know "why" its time to trade up.

I'd say it depends on how much you still enjoy driving the car, because you will get next to zilch for it in sale or trade. It has clearly given you a lot of pleasure over all those miles, so, in a way, continuing to drive it is like playing with house $$.

+1

Don't waste the effort on swapping in the 3.8L since you won't get any of that out due to mileage on the chassis (also not Cayman)

If you are thinking about it from an overall financial standpoint-- no brainer- keep your car.

If you really would enjoy a 981, then get a 981.
