I'm interested in buying a 4x4 first generation Blazer/Jimmy. I was wondering what types of things to look for when buying one. I'm not buying one that has been fully restored or anything, but something probably in the $2000-$4000 range. What are the typical problem areas? What are some good places to find out information and aftermarket parts prices on them besides the 67-72 resource page? Any help or information about these Blazers/Jimmys would be very appreciated.
