I purchased this beast from a friend and he now regrets that he sold it. Since then I put 18" wheels and tires (255/45/18 front & 285/40/18 ZR rated tires)use the best lubricants to keep this beast happy. So far, so good and it can sure fly. I already had it up to 150 mph and it still rides like you are going 80 mph. Safe and quiet! And this beast is 12 years old. Still get looks and asked questions at the fuel station. If you can, obtain a 1992 500 SEL!
