The first front wheel drive Cadillac was the 1967 Eldorado. It was based off the 1966 Oldsmobile Toronado. It was a neat concept back then but it went over-board! In 1980, the Seville went to the front drive platform. It was and has been everysince
the 4-door version of the Eldorado. In 1985 the entire Cadillac line except the Fleetwood Brougham
went to front-wheel drive.
In the 1980s, the emphasis was on fuel efficiency. I was amazed to see Cadillac stay in business considering all the dumb decisions by GM. Remember the 4/6/8 350 engine in 1981? It was to use 4 cylinders going downhill, 6 on a straightaway and all 8 uphill. Neat idea for a James Bond movie maybe. These had a problem getting stuck in 4 cylinders! Some people were getting rear-ended trying to get on the freeway!
Then there was the gas/diesel engine conversion. GM didn't even use a real diesel engine! It was a 350-gas engine converted over to diesel.
Then there was the Cimarron was a Cavalier with a Caddy hood ornament and nicer seats. That was a joke in it's self.
Lincoln has always made quality luxury cars. Even in the 1980s when everyone was making garbage, the Lincoln was still a pretty durable car.
When every GM gets something right, they stop making it.
