My first car was a Mk5 Cortina, W Reg, 1980, midnight blue, 6 years old when I got it and like Swiss cheese. It was almost like it was there one day, gone the next with rust.
My dad never had a car, he had scooters though and the one I remember was a 225CC (I think) Lambretta, in bright orange, with a fibre glass sidecar. I loved being in the sidecar, from about age 6 (1973), the world was my oyster, it was an F1 car, a boat, a fighter jet, a bobsleigh, and when Star Wars released (was that really 77?), a Millenium Falcon, X Wing fighter, or if I was in bad mood I was on the Darkside.

The sidecar was rarely, in my mind, a sidecar.
I was riding the scooter by the time I was 10.
That sidecar/scooter met a sad end when somebody flicked a cigarette into it, it smouldered then erupted into flames a while later, being fibre glass.
I remember 70's cars though, my dad's friend had a black Capri, 1.6 GL. It was beauty back in the day. He also had a Vauxhall Viva after the Capri. This was back when cars were easier to work on, I remember assisting with a gearbox removal from the Viva, I'd have been about 12 or so. I vaguely remember him having an Austin Morris, pre Capri.
