I just bought a 1990 75 2.0 TS here in Ireland, had spent alot of its years in the UK and here is what I found - hope you're sitting down :
Usual stuff, the salt grit doesn't help the rust problem, on my car the bad points are ;
Boot - Rust in the RHS rear corner, wheel well rusted but not too bad, rear arches gone at joint to sills, haven't removed the plastic sills yet, might just leave them alone too !!!! Jacking points - where are they !!!
Water in the passenger footwell, afraid to look at the floor. Electric windows not working in rear, mirrors, etc.
I don't mind as I was looking for a long term project car and this one has a very sweet engine. The Gearbox is vague, may need synchros but have a spare box, will whip out 4+5 synchro to replace my 2+3 if have to ...
I'm a newbie here so dont go by me, just saying, we all can take good pics of a car to get it sold.
If you buy, there are some real good guys around to help ... as said, I'm a newbie but already I think I have people to help if I get stuck ...
