Definitely a lot of car for the money. If you wait until the 2009 model year, you can get one without the dreaded IMS bearing. More cash, but I’d sleep better without thoughts of IMS bearing implosions dancing in my head.
Sadly, this particular example appears to have been in an accident (according to the Carfax report), so if you’re truly in the market you should probably skip this one and look for another accident-free specimen.
I would also point out that you can get a really nice 996-generation 911 for this kind of money, even one that’s already had its IMS bearing replaced. It’s perhaps not as “pure” as the Cayman, but by God it’s a 911.
