I have 21,000 miles on the car in 9 months. Drive it in good and bad weather alike. Have been at the 167 mph limiter over 100 times and drive it very hard. have only had to add 2 quarts of oil for the entire 9 months I have owned it. had no problems mechanically or otherwise and will be having hamann making it their demo car for Auto Shows and the such this spring. Definitely a LONG-term car.
