And if you can spend the money to buy an M3, $10k is really just a drop in the bucket.
That said, my point is that these two cars really aren't comparable because of what they cost and what you can do with them.
Here's my 2013 M3 with the ESS VT2 S/C making 5.0 psi racing a full bolt-on n54 335 with an e85 fuel-system conversion making 20+psi. So basically this is one of the fastest stock turbo 335's in the world. Let's see how it stacks up to an M3 with 5psi:
Oh, and the beating would be worse if it was a stock M3 vs stock 335.
