Basically I love to drive my Riviera with superb handling in year around Southern California weather. The interior is outstanding with all the needed controls on the steering wheel. On the down side, this is the only vehicle I have owned that can need repairs by just sitting in the garage. The mechanic bills have been frightning since I purchased it five years ago with apx 64,000 on it. I now have apx 95,000 on it and have put some $12,000 in it for repairs. Still love it!
Outstanding power on the feeways. Unusual interior comfort. Supercharged engine. Good gas milage.
Wind very noisy when windows are rolled up. This should be addressed if the Riviera is ever brought back.
