First off this car or at least mine has a tank size of about 13 or 14, not 16 and gets 26 mpg on the highway you can freeway drive about 4.5 hours w/o gasing up. It doesn't do steep hills at freeway speeds well (rpm goes through the roof) but most other cars cant or don't either. It's a great little car with good visablity and handles a canoe on top like a pro.
i did not enjoy the chevy tracker i purchased . the gas mileage was not good and the brakes sucked on gravel roads . needless to say the day i rolled my tracker in to a ditch , it was totaled . the trackers are way too light in the rear end , especially on gravel roads .
This is my second Tracker and they have both been wonderful - not even a lightbulb went out on my 2001 in three years of ownership! - I find it dependable, fun to drive and just what I was looking for - all for a very reasonable price. The back seat could use a bit more room, but then, I don't sit back there, so I don't really care!
