According to the DVLA the car was first registered on 6/2/1970 and the last V5 was issued on 1/6/2005.
According to the RAC the last owner change was 12/4/1997 and there were 6 previous owners, but this may be out of date.
I've seen that car on the other site. Looks very nice. It would be the one I'd buy if I didn't have Tom's moggy to keep us busy for a while. Be interested to know how you get on.
