Not really, done the odd mod that I've regretted. Blunders that come to mind include putting 17in TSWs on my R5 GTT whoch rubbed like a bugger and a single piece rear door on my MK4 escort van which was just a bit tacky... Most easily sorted and the wheels only lasted a couple of weeks on the R5 before they were changed. Now I don't mod cars and just keep em stock
