I'd love to say I had a great experience with Vossen. The CV4's I got look great on the Model S. But unfortunately it looks like they don't want to honor their warranty on a defective wheel. One of the 4 wheel I got was out of spec on the balancing machine for not being round. I had just waited 6 months for my car and this was day 2. Another forum member met me at the shop that installed them to buy my stock wheels and tires. So I had the option to either back out of the sale and remount tires and TPMS on the stocks, leave my car on jackstands for a week or more, or put the wheel on the car and deal with replacing it later. I chose to mount the defective wheel. According to the warranty on Vossen's website, there's a 5 year warranty for defects. Apparently that is only valid if you leave the wheels in your closet for 5 years. Very disappointed.
