To the poster who posted above. Where are you based?? I've a 2005 Fiesta I bought with rusted sills. Looks bad to me but I don't know anything. It's been welded to pass MOT but looks worrying to me. It passed Dec 2023 before I bought it and I've just got timing belt, service, new clutch and 3 new tyres because I thought I could get a few years out of it.... Pics can be taken if anyone is able to help give me some advice?? New here and doing this on my phone, bear with me, I'm used to a PC for forums.
