I have to say, that I owned an 85 Deville and it was one of the best cars I had ever own at the time (1996). But after have a few problem with the trans, then having it repaired, the car hadn't been right since. Years later, I searched for anothe Caddy and came across my "97" SLS. I could not be happier. I love the ride, the look and just pure enjoyment when I drive it, either in the city or o ...
I love the car. I stand firmly beside GM and Cadillac. The Northstar has a bad reputation but on the contrary it is a well put together engine,and will last 200,00+ if treated and driven the the Fast luxury cars they are.
Engine is made to fail in a major way between 80,000 to 100,000 miles and if G M can't do any better they need to fail. At least Toyota would have recalled this problem and fixed it but G M keeps sweeping their problems under the rug. I love the shape of the car but can't keep up with it breaking down. I will not own another G M again.
