Nice IROC! I wanted one in highschool along with a corvette and settled on a corvette 10 years later (1981).
Both the IROC and SUV probably do not get great gas milage to begin with. More storage space for computers in the SUV atleast.
Have you driven it enough to notice if the SUV needs front end alignment or makes any odd noises? Not sure whats worse a collision or being submerged in a flood for a week like the thousands of cars after katrina. I would be worried that the people who repaired it might not have done such a great job. Better get that side mirror replaced, around here they will ticket you for that. All in all it looks pretty nice, I asume the interior is nice as well.
