I bought the car used with 110 k and put new tranny in @ 115,000 k. It's needed front end work pretty much regularly. Ball joints, etc etc. The 4X4 is great! I got really good gas mileage until the fuel pump went out, now it's the standard 16 mpg.(was getting about 21mpg before!) The interior has nice luxury features. My favorite being the auto shut off of any light or anything plugged into the charger so the battery doesn't die. Blazer now has 150,000 plus miles and the radiator is rusted all the way through to heating coils etc. Have really had limited problems and been very reliable considering the lack of upkeep on maintenance due to financial difficulty.
Battery saver, outside temperature and direction you're driving
Better gas mileage for sure. Better quality, I have put far more money into this than I could ever hope to get in reselling. Unfortunately will take the loss to avoid the cost of upkeep.
