A clio I was looking to buy quite cheaply has a few issues, one of which is rusty sills. The rust is on the rail type bits that stick down from the sills. I know that's a crap description but you might be able to tell what I mean from this photo (crap photo as well), it's the black bit in the photo I mean.
The black bit is quite rotten for the length of the sills on both sides and I just wondered roughly how much it would be likely to cost to have this fixed so that I wouldn't have any problems come MOT time, as I guess this rust would spread to the rest of the sills?
Are the rails even needed for the mot or could they just be cut off?
Thanks.
