From Google street view it would seem that the same houses are still there - Palmers Way, Cheshunt. And selling for typical outer London prices, particularly since that nasty car company has moved elsewhere
It's odd how you can compartmentalise these things as I've been looking at the photograph with mature Elan owner eyes and forgetting that back when the factory was in operation I used to go to school daily on the railway line that runs behind Delamare Rd, getting on/off at the next station. I only lived five or six miles away and used to cycle into Cheshunt / Waltham Cross frequently. If only I'd known I could have nipped round with my Kodak and taken a few pictures.
I probably didn't notice the cars as I was too busy either doing my homework or looking at the girls from Herts and Essex Grammar.
