Aftermarket parts are an awesome idea to make your Smart car more unique than any other. Although some aftermarket parts will void your current warranty, the aftermarket part should come with a warranty for itself. IF anybody needs any recommendations for anything about their smart car, please feel free to ask. I researched into the smart car for 6 years before mine finally arrived and was one of the first people to put my name down for the reserve once it came up. I am currently working on a new audio system for the current premium sound package and working on a new exhaust that will increase all around performance. If you want to ask questions on where to buy rims, radios, floor mats, or anything, again, please feel free to write to me and I will give you my advice and where and how much for the cheapest price. Or, you can just write to me just to stop in and say hi because I won't bite.....my smart car will!
