We flat tow a 2004 Chevy Malibu that weights about 3,200 pounds. It has a little over 145,000 on the odometer, and has been towed almost the same distance, including to Key West, FL, Fairbanks, AK, and an awful lot of places in between.
We get a little over 30 mph on the highway, low 20's in the city, and about the biggest repair, other than going through a lot of brake pads (thanks, Dobbs Goodyear, for the lifetime pads!), has been replacing the alternator this past winter. We've been talking about trading, but I can't figure out why we should.
