congrats on the purchase! I personally love my W124 to trade it in for anything in the world. Even when I do want another car in the near future, I would still keep my car and store it somewhere. I simply don't like the fact that someone else is driving my car after I customized it so much. Even worse if the new owner is an idiot and rices it out really bad or crashes it...

The C43 has a lot more potential and it's lighter too. Add a filter and take out the resonators. It's pretty much done up for you!
