The Ruiner in GTA V retains its design from GTA IV, with only minor changes. It now features a quad exhaust, instead of the dual exhaust present on the GTA IV version. It retains its T-Top roof, however, as of Patch 1.29, there are now three different types of roof: with solid roof panels, with glass roof panels and without roof panels.
It always spawns with its windows rolled up, even without roof panels. The turbo hood bulge is no longer available and a traditional ram air hood (similar to the Buffalo from San Andreas) can be applied to it instead. There have also been minor changes to the badges and decals.
