Buick Regal GS
Contrary to popular belief that the 1990s were such a bad time for GM, there were actually many unique cars to come out that decade. One such car was the Buick Regal GS which took on a modern look and feel. But it was the Supercharged V6 engine under the hood that still stands as one of the most reliable engines that GM has ever sold (via LS1 Tech).
The Regal GS did everything that a sports sedan needed to do right, and it had great styling to back it up. It’s not uncommon to see one of these Buicks from this era with well over 200k on the odometer. It’s safe to say that these cars will still be on the road in one form or another long after EVs become a more common thing.
