My brother has a Wrangler with the 4 cylinder (it's a mid-90s model)...I own a 99 Wrangler and a 98 Cherokee, both with the straight 6...The 6 is a heck of a motor, neither burns a drop of oil and both have 115,000 plus miles on them...
Want some good advice??? Stay away from the 4 cylinder...When we go to the Outer Banks it's a joke how little power they have...
If you are going to buy anyway, check the radiator, they are bad to leak around the top...
