Just joined your great forum and just put down a deposit on my first 1997 300tdi XS. Great condition except for the usual discovery rust places you talk about on the cills, inner front footwells and rear arches. It's from a small dealer who is going to service/MOT it for me and have all the necessary welding down on these rusty places to get it passed. After reading the Forum it seems sorting out the cills and inner arches etc seems to be expensive. This guy is going to pay for this to be done, but once sorted is it permanent? My question is: if they weld and sort out all these rusty places for the MOT and I then look after it, (underseal, etc), is it going to last or will it just be a temporary repair and at the next MOT I'll be faced with more welding and expense, (but this time I'll have to pay!)? Should I walk away and keep looking, (not many good ones around in North Scotland), or once the welding work is done should I have a good machine that willl last a while? Thanks for your help.
