All of them are high mileage, most are over 200K.
The wife's 1999 Chevy Venture, 3.4 V6. 225000 miles, original engine, original transmission. It's had the lower intake gaskets replaced, one alternator, one A/C compressor, one brake booster and that's pretty much it. It's past due for front end bushings. It's been one of the best cars I've ever owned. With pretty much zero maintenance and heaps of abuse from my wife and kids it just keeps on trucking. It was wrecked a month ago and replaced with a Jeep Liberty. Buy back from the insurance company was $430, so it's going to get put back on the road or turned into a Lemons car. I haven't decided yet.
1993 Buick Roadmaster. 248000 miles, 5.7 V8. Engine looks to be original, as does the transmission. I bought it at 240K with no service records, so before then, who knows. I've replaced the coil and the HEI module.
These are my work vans. They are run hard, always loaded and minimally maintained.
1995 Ford E150. 350000 miles 5.0 V8 Original engine, second transmission. The rear axle has been rebuilt. That's pretty much all I've done to it. It's a piece of junk, but it's a back up in case one of the other vans goes to the shop.
1999 Ford E250. 435000 miles, 4.2 V6. I just had to put an engine in this one. The previous suffered a blown head gasket that proved to be terminal. Hydro locked and bent a rod. It's on it's second transmission. It's been through two alternators, and about five radiators. (Don't buy the Chinese junk parts, I can do a Ford E250 radiator in under 20 minutes.)
1997 Ford E150. 285000 miles, 4.2 V6 This one got an engine at 215K. A intake gasket failed and filled the crank case with water. My business partner drove it for a month like that. Needless to say it didn't do the bottom end any good. Other than that, just maintenance.
2002 Ford E150. 324000 miles, 4.2 V6. Original engine, original transmission. I had to replace an axle and bearing a couple of months ago, but it's coming due for a rear axle replacement because the ring and pinion are starting to whine and the shop that did the axle replacement thinks the housing might be bent.
The rest of them are in the high 100s as far as mileage.
1995 Camaro. 160K, 3.4 V6. This is my daughters DD. It had the engine replaced just before I bought it. I've done the clutch, had a rear axle and a couple of wheels replaced after my daughter smacked a curb with it at a high rate of speed.
1983 RX-7. 185K Rotary for now. It's blown up and in the planning stages.
1989 Thunderbird SC. 165K, 3.8 Supercharged V6. I don't know much about this one. I've had it 6 months. I have put a clutch and fuel pump in it so far. There is a chance it may end up being a engine donor for the above RX-7. We'll see.
Just bought is a 2002 Jeep Liberty. 170K. Original engine and transmission. It runs like a top. We'll see how long she lasts. I've never owned a Jeep before, but it looks to be pretty well built. Repairs so far, none and I hope it stays that way.
