Mainly depends on what the structure is like. Usual stuff, chassis, bulkhead, etc. If this is all sound, then £1400 is cheap. If it's rough, then it is expensive! The interior looks a bit messed with (holes in dash, stalks with boots pulled out, etc) Worth having a look at the general state of the wiring. This is one of the most important things for reliability. The outside shinyness is nothing to go by as I'm sure you know.
