During the 1980's my wife and I owned two interesting vehicles. The first was a 1966 Ashley Midget that was converted by Ashley as a demonstrator,  it is SORNed on the DVLA database and had a new V5C issued in 2012. In August 2019 I got an email from a chap in Cornwall who still owns the Ashley and intends to put it back on the road in its original colour and with wire wheels. 
The second was an NG TA which I built using all the running gear from a 1967 MGB GT, I did over 30,000 miles in it before I sold it in the late 1980's as I went abroad to work for several years, according to the DVLA it has not been taxed or SORNed since September 1998.
