The one picture is showing it is running a little hot. Maybe I'm not looking at seedo milage right looks like it has over 100000 Miles. Price seems high, but they will probably get it the two door will bring it.
The dealer website has the Carfax which shows that it was imported from Mexico. That may explain the “unusual” options on an otherwise base trim - power windows and locks but manual (88-94) mirrors, tailgate but no rear wiper, Silverado trim console with vinyl buckets (unless someone added it).
I’d think that the roll cage was added by someone.
