A guy I know got caught driving drunk with no licence, MOT, or insurance (can't remember if it was taxed at the mo but I'm guessing not) and 7 people in a car designed for 5. He got a years ban (from a licence he didn't have in the first place!) fine and court charges totalling about £500 and was ordered to attend a drink driving aweness course thingy, which he never actually went to and never had any comeback about!
To be fair this was a fair few years ago, so maybe things have toughened up slightly, but that's just rediculous.
By the way Shady - it's your responsibility to know what mods are on your car, even if they were on there when you bought it - most companise won't charge any extra just for wheels anyway.
