So I am in the market to buy a used Avalanche.

I was brought up to avoid cars/trucks with over 100k and used to not see vehicles at "reputable" dealers with high mileage. As I am looking now I see tons of dealer selling trucks with over 100k. I even see new Chevy dealers selling them with over 125k. My old school upbringing says at 125k, its got 25k left in it. I usually go to my dad and his friends (they all are old school mechanics and service guys, think 70s and Monkey Wards), they are of the 100k is death school of thought.

So what's the deal? Are Chevy trucks with over 100k worth buying? How many miles can I really expect to get out of a truck these days (assuming well maintained)? What should I really look at if considering a higher mileage Chevy?

Good question.. when I was looking for a new/used truck, I had similar feelings, warranted or not. I kept looking until I found my current 'o5 Z71 ( back in '08) w/49,840 on it. The lower millage trucks are out there but you have to do some looking.

When electronic fuel injection hit the scene that pretty much did away with "100K and the engine is ready for a rebuild" because the far more accurate fuel mixture adjustments prevent fuel washing down the cylinder walls and wearing the bores & rings out so soon. Seeing anywhere from 200K to 300K out of one of these engines is not out of the question, given proper care, and some have gone considerably further.

Transmissions are another story and at 100~150K you should probably assume if the transmission hasn't already been rebuilt, with proof, that it belongs on the suspect list for things that might possibly cost you a chunk of money in the near future.

Suspension work can get expensive too but in my experience, GM fullsize vehicles from the late 80's-on tend to be good for about 200K before anything serious needs attention. An exception would be the sealed wheel bearings on the 99-up trucks (and 4x4's from about 10 years prior-up) seem to be about 100~150K and they're toast but they're fairly easy to replace and not horribly expensive.

I had a 93 Silverado that I put over 230k on, My 01 had 189K on it when I sold it to my friend. He just went over 210k, and is still going strong. My friends 95 has 205k, and only blows a little smoke on start-up.(valve seals that I'm going to replace for him soon.)

Nowadays, they last much longer with regular maint. Just my humble opinion, of course.

A well maintained vehicle that hasn't been abused will last well over 200,000 miles. The old school thought of 100,000 is wrong, especially these days. 100,000 really wasn't the death knell back in the day, but people tended to stay away from cars with 100,000 plus miles. The reason was that carbuerators were not very efficient and you got more fuel washing down the cylinders and decreasing the effectiveness of the oil and caused more wear on the cylinders.

I think the oils are better these days also. The gas isn't though.

Go back 50-60 years and by 100,000 mi most cars were on their last legs. As said that no longer holds true. Technology has greatly improved longevity

I bought my wife's 03 Yukon with 108,000 on it and bought the dealer warranty for $1200. In the last two years, the A/C and the tranny went. I bought the warranty in case the tranny went, the A/C trouble was a surprise. I had it repainted but the front bucket seats need to be recovered, those wear pretty aggressively. Overall, it's still a good truck.

The last three company vehicles I had all went over 300k miles. The 95 and the 98 suburbans both had transmissions replaced more than once. The 01 suburban original transmission went out at 384k miles after the crew hit a deer and broke the trans cooler line. The only difference was the 01 had a factory external transmission cooler and the first two did not. I didn't put all those miles on them. They were hand-me-downs from the bosses.

The 06 silverado I drive now has 175k miles on it and has the transmission cooler. I feel certain it will be good to 300k+.

Other than rusted brake lines which is not a problem in my area, most any current GM truck with a transmission cooler and good maintenance should last 200+ fairly easily. Just my opinion.

01 has 255,000 on the ticker and still running great. Everyday driver work truck. Only thing that had to be done was a rearend rebuild due to a pinion seal leak.

04 has 115,000 and runs perfect. Its my weekend driver and I expect it to last everybit as long as the work truck seeing that it is babied compared to it. Time will tell.

A big reason transmissions are an issue is because most people never pay any attention to them.

Never have it flushed
never change the filter
Never even check the level

People fuss over what oil to use in their engine and never change their trans fluid.

I have owned FEW vehicles UNDER 200K. 200K is the new 100K. Many new cars come with 100K powertrain warranties. Many warranty companies will sell you a warranty to 200K or beyond. I have driven 200K trucks from the 00s that were tons smoother and nicer than 50K trucks back in the late 80s.

I look at it this way. If the vehicle makes it to 200K and doesn't look like a bomb went off inside and under it, then it was taken care ENOUGH of over the years that it will continue to provide reliable service if cared for reasonably.

Over 200K vehicles we've had include:

1975 Old Cutlass Supreme (222K, my first car, body shot but drove great)
1984 Chevy Suburban (222K when we got it, 230K+ when sold, drove fine)
1988 GMC Suburban (210K I think, drove fine)
1988 Buick Century (231K when sold, still running when subsequent owner traded at 252K)
1989 Buick Century (239K when impounded for expired tags, drove fine)
1989 Ford Escort (340-somethingK when I got it, 351K when I sold running for double what I paid for it)
1990 Pontiac Trans Sport (248K and odo broken for 3 years and roughly 40K when I got it, drove fine)
1995 Buick Century (270K when traded, drove fine)
1998 Olds Silhouette (204K to 208K, this one WAS shot, put in a used trans and rebuilt the top of motor and still scrapped it when it began knocking)
2000 Dodge Durango (172K when we got it, 224K now, plan to keep to 300K or more)
