They are commanding a higher price tag because of the amount that are left. There is literally a 1/4 of the fiesta rst's vs a s2 erst!!!

Also there is a really low count of RS1800s left and they are climbing in price dramatically this last while!

There are plenty of S2 escort rst's left, hence why they sort of flattened in price!!

And i don't blame people asking good money for a good frst. You see plenty of cossies on passioncosworths commanding daft cash, and regardless of outer heritage etc, a frst is a darn sight less frequent on a road or in a for sale advert than any cosbang
