I have owned my S -Type for 7 years and love it. I am sure this is not unique, however, may be of interest to fellow owner members.. My Dec 2003 S - Type, through initial and visually corroded, bubbling lower wheel arches - on closer inspection, more work was required. The outcome is both outer and inner sills to be replaced, both rear arches and the drivers floor pan section. The work is being undertaken by a highly competent fabricator and welder based at Crossways Garage Bodyshop, in High Woodsford, Nr Dorchester. The likely cost is circa £2.6k inc vat.
They are taking photos prior, during and on completion. The emphassis is upon the strength of steel used / pre formed or fabricated (to be confirmed with the welder) , the protection prior to welding and the addiditonal protection after welding, and of course the visual finish of the arches. Others, I know, have faced this dilemma many times - is the car worth keeping? In my case I think yes. i have spent on the services / maintenance of the engine and underside components, over the year,it is three owners (including me) - always previously serviced by Jaguar / specialists, is 3.0 petrol, in seafrost green, heated seat, heated screen and electric lumber supports.............whats not to love?.
If i can assit others in recommending the bodyshop or with more detail feel free to ask me, i shall do my best to assist.
