Now that I've got the heater working properly, the cold is no problem. The new dash I'm working on will also fix the demisting problems. Other than that, toasty warm, and just as much a pleasure to drive as at any other time of year. Needs more trips to the car-wash in winter, though.
I think it's chassis 50, to be honest I have not really taken much notice. I bought it off a chap named Malcolm in SA. I've been dreaming about these things since I was a kid, and now I've got one! (actually I've had it a while now, just never got around to joining the forum)
Cheers
