My 20" Avant Garde M621 wheels are for sale. $2000 picked up in Los Angeles or Orange County. I will not ship these! They are a gunmetal color and look absolutely fantastic on the Model S. The front tires have some tread left but the rear tires are done. The wheels will come with tire pressure sensors (TPMS) for cars built prior to September 2014. Of course, you can put your own TPMS in if you have a newer car. The wheels also come with wheel locks and a socket key to keep them from getting stolen!
