Best car of I have owned in my 58 years of driving
in every way.
I have a '94 Park Avenue Ultra with 296,000 miles. It has never had any major engine work done on it and it runs extremely well, with excellent acceleration. I't the most comfortable car I have ever driven. I also have an '89 Lesabre with 380,000 miles and it's never had any major engine work done on it; runs smoothly still. You can't beat a Buick and the 3800.
