On Monday my car goes in for MOT and passes. I decide not to get it serviced cos im a cheap student, thought id do it myself. I went to halfords yesterday and got oil filter, oil, air filter and a fuel filter. So, we borrow a trolley jack from this bloke and my boyfriend starts to jack car up, just as i bend down to put axle stand under car the jack slips and the car falls and the sill part lands on the jack. The sill under the passenger door now is bent!! Needless to say my (nearly ex) boyfriend is in the doghouse at the moment. I thought Id save myself some money doing it myself but instead i have a bent sill!!!! The sill is not cracked just bent, how much do you reckon to fix it?
