I am buying an E320 tonight. It is a 1994 and mint. All books and records. I am pleased with this purchase, even though I really wanted the performance of E500. My question is this: Can anyone tell me what the differences are between an 1994 E320 and a 1994 E500? Besides the V8 engine and the different back seat? What are the body differences, if any? Suspension? Options? any help will be much appreciated. The E320 is very nice and drives well, but l of course I will want to do some performance upgrades.
