I bought my s10 with 94k. after i bought it the alternator went out. i replaced front pads, rotors, and wheel bearings at 100k. new tires and front ball joints followed at 130k. i've replaced the fuel pump twice. the truck now has 160k with no signs of stopping. its a dependable truck. parts can be pricey but with proper care, the truck will last as long as you want it to. gas mileage is great, its under powered with the 4cyl, but id prefer the gas mileage over the acceleration. if planning on lowering it like i did, be prepared for suspension components to fail.
I bought this truck about a year and a half ago with 100,000k on it but I've owned an S-series vehicle before, so the mileage didn't bother me. I've driven it almost 40,000 miles so far and I really don't have any complaints. I only had to replace the MAF sensor and heater core, and I've done everything from auto-crossing to drag racing with it. I've put it through its paces thousands of times and it hasn't given up on me yet. It is definitely a truck that is decently easy to work on if something goes wrong. I've averaged around 20-21 mpg driving 50% city/highway. It's decent for a v6 truck.
This truck is a piece of junk. At 44,000 miles I had to replace the water pump. At 46,000 I had to replace the trans. The handle for the seat to recline broke soon after I bought it. I also had to replace the breaks at 25,000 miles. My wife has a 01 f150 that pulls a fifth wheel and it had 60,000 before the breaks went out. Also with 100,000 miles the trany is still going strong. My son has a 87 f150 and has less problems than I am having with this piece of junk. He has 250,000 and his trany is still going strong. This is my last Chevy, going back to Ford. Like a rock my foot.
I bought my 2000 Chevy S10 regular cab truck in 2003 and I STILL have it in 2016... It had 12,000 miles on it when I bought it & has 148,000 now.... I"ve replaced a battery & and alternator. OVERALL, I love this truck... It isn't the greatest mileage (low 20's) for a 4 cylinder 5 speed, but it has been mega dependable... AND I DO tow with this truck My trailer is 16'long x 6' wide & I have FILLED it with thousands of bricks and yeah, it's lugging along, but she DOES THE JOB... I'm not planning on getting another truck... I hear stories about newer vehicles & am NOT thrilled with the quality... OH.... I see even newer trucks where the clear coat is peeling & flaking.. I live in Phoenix AZ and I STILL have my nice shine.... THIS truck has been great for me. I would NOT want the larger engine... due to lower gas mileage. I don't drive like a race driver... and I have NO problems merging onto freeways safely at the current speeds... I bought mine at auto auction for $1,200 yes $1,200.
