I'm shopping right now and expect to buy within a month or so. I looked at an '08 base yesterday with 15k miles. It was at a small car lot and the guy said it had not run in about 2 weeks. There was a pretty noticeable tick coming not from all holes but from maybe one. I didn't drive the car but it did run until the temp gauge started rising and by that time it had gotten better. I'm a mechanic and have heard a ton of valve trains in my days, even had a '71 911T. This is the first Cayman I have heard running and I want to know what to expect as I look at more. Thanks and I hope to be back as an owner, C.
