I have had my K-5 for 10 years and am finally thinking of trying to find a replacement (has not been easy). I have had some problems along the way - replaced the rear end in '98, new torque converter in '99, alternator caught fire in '97 - but in all it has been a great vehicle. They just don't build them like they used to. The dash actually has metal and vinyl, and is not all plastic like trucks of today. GM really needs to re-think their interior design for new models. If I had the money, I'd think seriously about restoration, but here in salt country (Central New York) it is impossible to keep the body going for ever.
I still drive this vehicle daily and have for 5 years. I bought the vehicle with 88K on it and the problems didn't hit until 135k. Then they really hit. The oil cooler began leaking like a sive, the headliner fell down on my head, #6 cylinder developed blowby that I couldn't keep spark plugs from fouwling. In five years I drove her to North Carolina and back twice, South Carolina and back twice and Missouri and back twice and Gettysburg and back without a problem! It rides and handles like a dream. I bought it for $5,500 in 97 and it doesn't owe me a thin dime. I still love this vehicle.
This Blazer has served us well. We bought it with only 33,000 miles on it, and still love it. It's been extremely reliable, and build quality has held up well on the dirt roads that we live on. The 5.7 L 350 V8 is amazingly quiet, smooth, and powerful. For under 10,000, the Blazer is a relative value even in today's market. I would recommend this vehicle to anyone. I wish that Chevrolet could bring these Blazers back.
I purchased my Blazer with 160k on it in march of 2007. I am still in love with this truck. Very reliable. I let my pregnant wife drive it 2,400 miles by her self and didn't have a worry. gas mileage is about 17 on highway and 12 in town. not bad for a truck that old. now i have 190k on it and still find every excuse i can to drive it. still runs strong and lays rubber. if you buy one u wont be disappointed!
