Not necessarily owned by me, but regularly used by me, and very memorable, for very different reasons!
I learned to drive in my Dad’s Vauxhall Victor estate car , which he used for work, but mainly I learned in his metallic blue Mk11 3.8 Jaguar with real wire wheels, which had a manual gearbox, with overdrive, leather upholstery ( black with white piping) , real walnut trim inc. picnic tables on back of front seats, etc and which went like a bat out of hell, and in which he used to ferry the family around in on the weekend, leaving me to use it the rest of the week!
He was a butcher, and the Victor had a certain strong odour about it, hence not using it for family occasions, and later he changed it for a Standard Vanguard Luxury Six Estate car, which I used to drive regularly.
Later, he also changed the cars for a Mk 9 Jaguar in Midnight Blue with grey leather and a sunroof, which I used every day and took on holiday etc, down to Cornwall, Germany, France and Spain and I bought a new Ford Thames (Anglia ) 5 cwt van which he used for work, whilst I used his Mk 9.
There have been quite a few more ‘memorable’ cars over the years!
