I am new to the Forum, as well as new to the Mercedes world. I have a 2003 Mustang GT, Modified of course. I also recently purchased a 2008 C300, and I am loving it...I am planning to build it, Performance wise as well as some minor exterior modifications, I.E Wheels and Have to do something about the tips...I hope I can learn much from the more experienced owners around here and gather as much information as about these cars as well.

 

Welcome to the forum and congratulations on your purchase

There isn't much you can do, tuning wise, to a NA engine, but I hear good things about Eibach sway bars to improve handling

 

Well thank you for the insight, I atleast want to do some wheels. Not so sure what company makes good Mercedes wheels.

 

Welcome. As already stated: engine performance mods (tune) are very expensive $800+ to get 20 hp (maybe). But it sounds like you already have a BadA$$ ride to give you the Power. So now enjoy the looks, style, and handling of the Mercedes.
Wheel choices are out there- just use the "Search" feature at the top of the page. The Offsets are extremely high on the Mercedes so make sure you follow suggestions. What size and style are you looking for?
