S65 vs S62 in an M3 GTR replica….. Seems much less authentic than going with an S62 (given year of development, implementation, and overall look).
However, you made some points about the GTR motor being more similar to the S65 than the S62?
I would go S62, but then again, I would never in my life do what you are about to so good on you sir. Im down to see an e46 with an S65 anyways
