2001 Buick Century Custom 4dr Sedan (3.1L 6cyl 4A)
I bought it as a second car to be used around town and local trips. It turns out I liked it so much, I use it as my commuter car for work. Gas mileage is excellent (26 mpg local and 30 mpg highway) and the V6 has plenty of power. What a surprise coming from a chunky Buick. Oh, and the comfort is worth it alone. The ride is very soft, so don't worry about fatigue, just be careful of the sharp curves. At 100K I replaced both axles, tie rods, one brg and did the usual 100k maintenance. There was some coolant loss, most likely due to GM's problem with the V6's, but one can of stop leak did the trick. Overall it's a great car if you don't mind the cigar jokes.
The ride, power and gas mileage. It's so much better then banging around in a tin can and shifting gears.
