i went through this same process just recently, unless you find one that's below $75k, i am not sure if it's actually cost effective. there was a decent 09 car that went in 2 days, had all the transmission fixes done, full bolts and tune which is about 650awhp, otherwise i am finding that the facelift model (MY11+) are about the same cost as getting an 09 with low KM but ends up same as an MY11 due to requiring all the fixes to be done.
I ended up getting an MY12.
