Going back to the first question - it's a 2.0 TS. If it was a V6, I would feel happier about spending more, as they will start to appreciate in value at some point. Not sure this will happen will the twinnies.
I did look at RX8s, and I drove one, but it wasn't that quick, and for the amount of fuel + oil they get through, it didn't seem worth it. My mate has an RX7 which is lovely, but that's a different car (rotary + twin turbo). I'm back at uni as a mature student hence my lack of cash. Hopefully in a year or two I'll be able to get a 4C :-)
