Yeah, nutz, you can do whatever you want to it.
Just for grins why don’t you just clean it up and leave it alone for a while before you do whatever you’re going to do to it.
By ‘clean it up’ I mean take the crap off the wheel well arches, get rid of whatever the hell that is on the roof, nice detailing, Euro lights with Euro wipers – or just as good remove the wipers altogether – paint the grill screen black, and add some nice 16 inch rims.
Then have a cooling off period.
126s aren’t like the 116s and 123s you’ve ‘fixed’ before, 126s don't need heavy mods to look good or more modern. (They’re already modern.)
It’s just a suggestion.
