The mpg was a concern for me too with the miles I want to put on during the summer months. Another was tire wear, I like the 18in wheels on the older c63s (cheaper rubber) but even 18s the weight of that car would shred a performance tire. I do like the idea of four doors a little more than two after getting my sti having the extra room is pretty nice.

Strangely I ran the nsx on auto trader last night! I was dumbfounded! Those were easily found for sale 6 or 7 years ago. In my price range I only had 4 hits! Ill do a little more research on them. I know they reviewed awesomely I'd have to compare it directly to the r8! I'm not a huge fan of convertibles it's scares me being so tall if I were to end up rubber side up I'd end up a statistic!..
