I puchased my 1996 Riviera in 1998 and still own it today. I stopped driving it full time in 2005. It currently has 164,000 on the odometer. It had 39,000 miles on it at purchase I averaged about 19,000 miles a year when using it as an everyday driver. I couldn't see trading or selling this car for the "book value" when it is still in fantastic mechanical and cosmetic shape. I now take to car shows and believe it or not a lot of people don't even recognize the car as a GM or Buick. They haven't made the Riviera since 1999 so there just isn't that many left driving around. I have trophyed in numerous shows and will probably never get rid of this car.
