Even if money was no object, looking back at all the stupid things I did in cars when I'd just passed my test (enjoying the handbrake a little too much etc
) I'm glad it was an old fiesta
I'd have ruined a GTI, chewed up the clutch, kerbed the wheels, thrashed it from cold and generally (sometimes unkowlingly) ruined it
My advise is buy something cheap that you don't care about for 6 months, until you get better at clutch control & knowing the width of your car, what to do when you push too hard round a roundabout, how to park in a space. . .
Then when you've got some experience, get the best one you can afford
Trust me, passing your test doesn't mean your a great driver (even thought we all think we are within 5 mins of passing). Experience is what you need. There's only so much you learn in a test, the rest you find out for yourself. In doing so, you wont be very kind to a car
