Driving an old car as a first cat isn't sensible, but it does teach you a lot about motoring. I started off in a 1955 Austin A30 which had no seatbelts, 28 horsepower and no real brakes. I learned to double declutch, plan my braking, cope with cross ply tyres and always cancel an indicator as there was no auto cancel. I also learned that nobody notices a trafficator any more so turning right at a roundabout was a little like Russian roulette. After six months of that I progressed to a 1959 A35 which had flashing indicators and had had seatbelts added. I drove this car until I was 24. I did all of the repairs on it myself and learned a hell of a lot in the process. I'm not saying I'm the Stig, but I'm reasonably handy in the twiddly bit. My opinion is that if you survive driving an old car as a first car, you'll be better off for it, but pre 1974 vehicles didn't have anywhere near the safety features of a "modern" car (post 1990). Good luck with whichever way you decide to go and above all, enjoy it.
