You can get a Cayman S with 20K miles for the same price as a new 370Z. One of those is the class leader and won't drop £10K in the first year of ownership, has a beautifully crafted interior, and has the engine in the right place. The other one is a Nissan.
Given that running costs will be approximately equal, I know which I'd rather have. If only the Boxster looked quite as good as the Cayman then I'd have had one of those over the 350Z, too. And regardless of jealousy, the interior on the 370Z is still very poor for what the car represents, it's just not as bad an original 350Z.
