I am heading off to the UK and whilst there will be looking at a few Sierra Cosworths to bring back.

I have been doing some homework but would be great if people could post up common problems or tell tale signs with them to keep an eye out for.

I remember reading a buyers guide for Cossies in either RetroFord or ClassicFord magazine a few years ago, will have a dig around and see if I can find it!

There is a RS500 buyers guide here which has some relevance to the standard RS as well:

One of the recent Octane magazines also had a buyers guide in it.

I have a buyers guide sitting on my desk from an old mag. I'll scan it and post it up tomorrow.
Bewdiful Moonstone pic btw... I just love the rims. Compomotive MO's if I'm not mistaken.

I have scanned the Buyers Guide from the October 1991 edition of Performance Car....
Unfortunately pdf is 29MB so can't upload it here. Have however uploaded it to my photobucket site as 5 jpg files. Go to:
