Are you talking 450bhp or whp? I don't think you'll see that 100-150HP gain n/a without MAJOR work. Intake, headers, exhaust, and a chip. That's about all you can really get. I think to to get to 450hp you'll need a dyno tune, and not anyone with an SCT can tune a mercedes, so that'll be pricey, you'll probably need cams and compression there. Rebuilding the motor with custom parts I guarantee you'll see the other side of $10,000. So you've got $15,000-$20,000 in the car. I'd buy the W210 because you'll get a good price from the fam, do some mild bolt ons, some suspension work and call it a day. As soon as you try to go insane on the W210 you're exceeding the cost of a W211 quickly
