Featured Car - Mark Tonazzi's 1987 Grand National

Super clean and super nice!

Mark is the second owner of this extemely clean GN. Mark loved more than just the car, since he ended up marrying the original owner's daughter! It's obvious that the original owner kept the car spotless for Mark, since Mark can tell stories about the meticulous care his new father-in-law lavished on the vehicle.

Mark's beauty is always garaged and covered, which explains why the original pain (treated with a Teflon coating when the car was new), still looks this good! It's never seen snow and only a few drops of rain when returning from a car show. All in all, a sweet ride, despite Mark's nickname for the car ... Satan!
