I've got a 76 XJ12L, and I've only got rust in two spots:

Lower back part of the left rear door, and a pea-sized spot on my front left fender, above and behind the wheel well. I don't have ANY rust around the windshields...front nor rear.

In answer to your question, "if it is starting to rust there in just alittle while will it be rusting everywhere or if i have that fixed will it stop?"

Two problems with asking this question where rust is concerned:

1. What area do you live in? Is it really humid? Really dry? A little of both depending on the day? Do you get a lot of rain/snow/fog?

2. You didn't say to what extent the rust is. Is it merely surface rust? Or is it a bubble of rust? A bubble will (more often than not) indicate DEEP rust, which would mean sheet metal replacement. Surface rust will mean little more than a good sanding (down to the bare metal, with NO SIGNS of rust anymore), then rust treatment and/or primer.

You should give the car a really good looking over. Check your battery basket, under the doors, under the trunk, INSIDE the trunk, inside the engine compartment, door hinges, etc. Go over it with the proverbial fine-toothed comb.

Another thing: I would question those actual miles. For a car that old, the odometer only has enough digits to cover tens of thousands (as opposed to newer odoms, that cover up to 999,999.9 miles). That's a 25 year old car, which would mean less than 2000 miles driven per year of its existence. I would question that (check the title for any mileage discrepancies).

 

Pictures are good (if you got them from the person selling the Jag), but a first-hand look is always best, if you can.

Post the pictures up, yes. I can tell a little bit better from them.

 

Yes, it's extremely common for the Series 3 models to rust at the bottom corners of both the front and back glass. I can be the sign of a bad problem. It just depends how deep the rust goes.

 

It is common but not the end of the world. I pulled the windshield on mine and repaired the damage. New gasket and put all back together. Friend did the paint work, you could not tell it was ever there. Every car in the world has an issue and this is one that the series 3 must learn to live with. ( counciling available when coping is difficult)

 

Mine had rust at the bottom of driver's side front windscreen. It gott fixed when I had it redone more than 10 years ago. Haven't had anymore problems. My car however lives in New Mexico. Nebraska cars are going to have ore rust problems. I used to live there. A low mileage car can be scary, might mean that it's spent it's life in the shop or it has been sitting for long periods. Mine has 210,000 miles and is my daily driver.
