Check the prices now! For a nicely restored one you can add a nought on that figure. In fact there are several up at prices over £200k now. But at the big money, you want a V8 manual, not a V6 auto.
I bought a red one and a white E-type FHC from a guy who needed the money in Cowes, years ago, when my Dad was living there. They were both average but I made a few quid. Probably should have just garaged them and watched them appreciate!
