This isn't really about a modification, but it's hard to find a forum area for stock issues that cover more than one model and this seems like the best fit. If you haven't checked yet, you really ought to look under the weatherstrip at your door sills.....you might find something disgusting like this: Those who've owned Gen1 MINIs for a while tend to already know about the well-documented door sill cancer issue, but people buy used MINIs every day. YES I do know it's been covered elsewhere but I don't care, I want a thread here on M/A. Besides, the best coverage elsewhere tends to have originated back when we discovered this problem and all started out as whistle-blowing and surveys to see whether it's widespread. The short answer is yes, it's a widespread issue. There, that's behind us. I'm more interested in suggested solutions. I've heard of people going to the dealer when the rust was just getting started and having the dealer wipe off the rust and tell them all they need is a little wax on there. I've also heard of people having work done in a body/paint shop either on their own or thru a dealer. There are other ways, more effective than wax and cheaper than a paint shop. So, for the benefit of others, how have you dealt with yours? How well did it work?
