9k+ depre for FD isn't that cheap; just because its '40k' doesn't meant it's cheap....
Might as well wait for 2011, then buy the FD from owner for 9k... but only drive for few mths

As to parts value, well, that's up to the individual to appreciate. Some people would rather get a stock car and do up, so the $40k there matters little. Anyway, performance parts going with a car as a whole rarely command a good value; maybe 50% or less of its original price.
My friend's FD was full of problems and he couldn't take it, so sold it off after 1 mth. Price was about $10k a year also.
