if it was the 1980s then it was probably a DHSS car, still very cool
(by one do you mean just an invalid vehicle in general or a Barrat midget?)
it was only until the early 2000's was there a big push to recall the remaining cars
before then if you had a Model 70' you could keep "leasing" it indefinitely, but the numbers slowly declined over the 80s and 90s as either Users passed away or did finally jump to the mobility scheme or just gave them up for one reason or another
Fairly sure it is, been a few weeks but it's a storage building off a roundabout in Llandudno Junction, always locked up and lately seems to be the storage for the audi and bmw dealer over the road. Great news if loads got saved there were a fair few there.
