General Information
My Blazer rolled off the generals assembly line in 1991. I've learned a little history about this particular truck mainly from the dealership. When I took it in for a recall, the service writer pulled the records up and told me a little about where it had been. She said according to the records the truck was originally purchased from a southern California dealership and was purchased as a fleet vehicle. Which may explain why it had so many miles on it, but interior wise was in such good shape. No tears in the seats, factory, original floor mats, etc. Now from there it gets kinda touch and go. Best I can tell, a guy in Vegas ended up with the truck. He sold it to the guy I bought the truck from, an airline pilot. He told us that he spent a lot of time between Vegas and Phoenix, AZ, so he bought the blazer to take to AZ and leave at the airport so he would have have something to drive when he was down there. He tuned the blazer up and took it to Macco to have a CHEAP paint job put on it. When he got it back he decided it ran to good (even with 232,222 miles on it) and looked to good to leave in the AZ sun all the time. He decided to sell it and get something a little less nice. That's when I came along, with some money and a 4x4 itch, and bought it for 4000.00 dollars. Now, theory here. Another thing I found out when I took the blazer in for the recall. The service writer asked me if I had ever had it serviced there, I told her no. When she looked up the vin #, she found out I hadn't had it serviced there, but the previous owner to the airline pilot had! Bonus for me, she had a good amount of the service records on the truck. The last thing it was in for was a complaint that the tranny was slipping. GM advised tranny was bad and needed a new one, customer declined to have repaired. But when I got it the tranny shifted fine and still has to today. When I first serviced the truck, particularly the tranny, it had what looked like new Fram filter and pan gasket. So here is what I think, tranny went out, guy got scared of the truck because of the high mileage, had the tranny rebuilt somewhere else, and sold the blazer to get out from underneath it before anything else major happened. That's when the airline pilot bought it. I think that's about it as far as the history of the truck, at least from my speculations.
This is a picture of the Blazer right after I got it, all clean and shiny.
