 Be carful of what gas An gas stations you use, but, either way no matter how well you keep this truck up, the Cadillatic converts are going to go out after 80,000 miles! $2000 in repairs. I have had two of these trucks so far An both of them needed converters around the same time. They are nice but they begin to have problems after 80,000miles or less! My friend truck has the same problem! This should be a recall situation because clearly this is a manufacture problem!
