Kayla: It's probably not a good idea to take £20K with you to see a car, just take a reasonable sized deposit. I'd imagine the majority of genuine Cosworth owners would accept a decent deposit and the balance in the form of a bankers draft. Wandering around with all that cash is far too risky in my opinion.

On advice regarding buying an Escort Cosworth.

Firstly do loads and loads of research.
Secondly when you ring up about the car find out as much as you possibly can about it. You can normally gauge what kind of person the owner is likely to be from a phone conversation. A true Cosworth enthusiast will want to talk about their car all night!
Thirdly when you do go to view a car take someone with you who knows about Escort Cosworths.

There are plenty of good cars out there, but there are plenty of dogs too, it's all about taking your time and finding the right one. Cars like this need to be bought with your head not your heart, otherwise you'll buy the first decent one you see.

Are you looking for any particular colour or spec?

Big or small turbo?
