Well Steph, I would print off the advice Wayne has posted in this thread to take with you for a start. All good points to check.
The car may be 1981 registered but it looks to be a Canley built car (steering wheel & front panel badge) which would make it a 1980 manufacture. If it is an 1980 car the VIN number should begin TPAEJ7AT followed by a 6 digit number - check the plate in the engine bay.
It does appear original apart from the non standard alloys - look like Austin Montego 15" wheels. Have you got a matching spare? Nothing wrong with those alloys but ask what other mods have been made to the car - larger alloys are often fitted to allow a brake conversion to be done. Again nothing wrong with that as long as properly done!
The interior does look original & again suggests a 1980 built car as it is the last trim style used. It may be the photos but the door trim looks a different shade of tan to the seats so may have been replaced - the door pull handle is on the wrong way round. Have repairs been done to the doors? Check the sunroof is in good condition - hard to find replacement parts if it is torn or damaged. By the way it is not a Webasto, the cars were fitted with Edrose roofs.
If the body is sound & you don't find any horror stories then I would say it looks a decent example but the asking price is a bit high - looks like the seller will haggle though! Take a look, take some photos & notes, & have a think about it before you take the plunge. By all means come back on here with any questions! Good luck!
Tony
