RS Cosworth Sierra 3 door - advice on values
New to this people so bear with me.
I've found two 3 door 2wd cosworths in original spec, one black with 32k and one white with 77k.
The white one is scabby with numerous rust spots but they're not perforated and he wants £6k for that. The black one's mint and he wants £10k for that.
They've both been in a garage and owned by the same bloke for nearly 25 years.
I'm looking for comparables but i can't find any so i though you might be able to help. What is a realistic ball-park figure to pay for a mint one and a rolling project?
Obviously I won't hold you to anything, just appreciate as many comments as pos.
Cheers, Tim
