I like the low maintenance costs of the Buick best. They aren't the prettiest car on the road, but are reliable. The only "defect" I dislike the most about the Century is that it is difficult to see out of your back window when backing.
Buick Century Ratings, Reviews and Analysis
Ratings & Reviews
If you need a good car for everyday use, get a mid sized Buick with the 3.1 v6 you won't be disappointed. I have four Buick Centuries so far and I will buy another one when my need to get another car comes along.
It had 93K miles on it at the time of crash. Mechanic had told me I should get 250,000 out of it with regular oil changes. I think it would have reached that had the accident not happened. Please read pros and cons above.
