I am going to go look at a 1991 80 series today but I have no idea what to look for on this rig as far as the goods and bads. I know that it has 175,000 miles. Is it a bad idea for me to invest in a compression tester to test the cylinders? The cruiser is supposed to have a 5 inch lift and 35" tires on it. What types of things do I need to look out for. I have never looked at an 80 series berfore. ??? Any help would be greatly appreciated.
