I confess I haven't had the covers off the sills but I will get that looked at. On the last MOT, about 6 months ago, there were no advisories or mentions of rust. However it is a good tip as it best to catch such things early. If there is a problem I am presuming the sills can be replaced or welded? Cost is not an issue now, whatever needs doing will be done.
I have not read all the stuff on the boards yet, some of it may be a bit too technical for my understanding but I will look. I have found out a lot about the S-Type from reading articles on the web and I think this car has suffered from just about all of the major common faults and they have all been rectified. The engine has been given a clean bill of heath by a Jaguar specialist and the transmission has been completely rebuilt. I suppose the big ends may fail, but if they did I would source a replacement engine
Some of my friends do not understand why I didn't cut my losses and buy a newer car, an XF or similar, but anybody can do that. I prefer to have something people will look at and admire, something I feel I have kept alive when others would have either scrapped or sold with its faults to an unsuspecting buyer who then may not have been able to afford to fix them.... I guess this is like "recycling"... good for the environment... but I won't pretend it is any more than a love of my Jag
