As odd as it sounds, it’s a tough one to define my first car.
First car I regularly use to drive was my dads Ford Sierra 1.8 LX (rear wheel drive, manual, no power steering!)
The first car I owned (but technically it was bought for me): Rover 214 (with beige interior, so cool!)
The first car I bought with my own money: a Renault 19 for a tenner (only bought it because it was a tenner - and did one journey in it (London to manc), and then gave it away to a mate for free.
The first car I bought myself and actually owned for a while: Ford Puma 1.7 (that was a fun car - be it a bit femine)
