I've acted like this before I'm old enough to realize that I should not be like this plus i don't know how the hell how to mod games like these and that I'm acting dumb plus (one thing to say) the XJR-14 and the group c C292 are have a similar body so just slap a Merc livery on that and it will look particle the same the only diffrence is interior and engine (prob weight to)
It's actually the Mazda and XJR-14 that are very similar (pretty much based off the same car),
