Anything 'short door'. £8k - £17k..... unless it's historic
Zetec..... £16k - £22k
Duratec..... £24k - £29k
Sigma... £24k - £29k....
There are a lot of 4/4's advertised for well in the £30k's, they've probably been on for many months though or are owned by dealers who paid too much. They won't sell unless they are reduced dramatically.
The odd low mileage 80th anniversary is possibly worth early £30's or a very late high spec 'bespoke' car, apart from that £30k is the ceiling for a 4/4........IMHO🙃
I'm happy to be told how wrong I am........
