As a long time owner of Suffolk cars ( I've had 3 ) and being quite involved on a personal basis with the Directors, I have found the whole event quite sad however that's that and we must look forward. A new company "Suffolk Classic Services" is going to look after the servicing and provision of spare parts for the SS100 and C Types but on a very much reduced size after all they only built around 350 SS100's over 26 years and they are scatered all around the world so the demand in the UK will not be vast.
As for JLR, well the Jaguar arm is now IMHO a pathetic relic of a once great car company. They built some of the most iconic cars in the world and over different periods had some of the worlds fastest cars but now, if you don't notice the leaper on the boot lid you could be looking at a Vauxhall or a Ford they are so non individual so I will continue to enjoy my SS100 and it's wonderful XK engine until HMG decrees that I'm no longer allowed to drive it.
