That's your truck, not a car? My Grand Am barely beats that! My truck gets 10 going downhill with a tailwind and drafting a semi.

The truck in my signature is on it's original everything. I've replaced the master cylinder, water pump, fuel tank selector switch, fuel pump, and valve cover gaskets. All other work has either been regular maintenace (brakes, belts, hoses, etc.), or an upgrade to a part that wasn't bad. It's got a 350 with a thm-400 tranny. There is not a single leak except for the front axle (pinion and shaft seals), which is out of a '78-'79. The body is beat to hell, but solid. The frame had light rust on it (angle grindered it clean, primered, and undercoated), but is 3/16" thick with no thin spots. Just shows what a little dealer installed rustproofing/undercoating will do. As far as I know, it lasted until a year or two ago when it started to chip off.
