Id definitely recommend against it.I have a 1997 Bravada, its the same thing as a blazer, just with different trim options.
Ive had it two years this month, and Ive replaced:
battery
starter
alternator
all new ball joints, idler arm, pitman arm
another new ball joint
broken abs line bracket
oil cooler lines leak
u joints
passenger side wheel bearing
sagging doors
dimmer switch
rear washer line broke, flooded the rear of the car
washer tank pumps both leak
broken motor mount
burned factory wiring
hood washer
Thats all that comes to mind, Im sure theres more. If you get one, check it over for the common problems for that year.
