Apologies for abandoning this thread, I got suspended for what seemed like eternity grr!
Decision was made on a 16v Clio, found a nice one lady owner in great condition not too far from home... then my parents got involved and gave me a good telling off for such a stupid idea.
They think if he get's his freedom he's going to become a criminal junkie like his Dad. Well, they say he may end up hanging with the wrong people blah blah - I basically said they know he's nothing like his father, he's a smart, nice, polite kid without a bad bone in his body, also that his in and out "curfew" will not change simply because he gets a car, that's down to our grandparents (who he lives with) and they hardly ever let him out the house as is, the poor kid.
Their other reasoning was that he is guaranteed to crash because he's a kid.

I explained about the insurance tracker box thing and how this will keep him grounded, the car is safe and slow, he will be learning to drive in it so will respect it from day one etc.
I tried my best to fight his case but nope, not allowed... so next year for his 18th I'm just going to keep quiet and buy him one anyway, he'll have been learning/driving for a year and I know he's a good kid so will be safe and fine.
Bloody irrational parental fears!
