Hi, i have started to find rust on my car and i am worried that this is the end of my car, can anyone tell me if this is correct or is there something i can do to repair this and stop it from being the end

i have enclosed some pictures

 

Why would it be the end? its just body rust. It is not like any critical components are rusting to the point of potential failure. Looks like all it might eed is some paint, and prime the rust spots.

 

I don't like rust issues at all . It may be much bigger deal even than it looks . We had a big problems on my XJ40 and and had to drop off the engine as well to clean all the rust out . If your rust only consists of merely the pics you posted above then I would not worry that much .
However , I must stress that you need a good inspection if you like to drive your Jaguar safe and sound and long ways
