Just make sure you give the car a good going over when you get it back mate.
My Dads old motor got repaired by the insurance companys 'approved' bodyshop and seriously it looked like it had been prepped and painted by a bunch of 3 year olds!! The paint match was non existent, they had used metallic instead of pearl (black) and the prep looked like it had been done with a yard broom in a sand storm!!!
Dont accept it unless your 110% happy. Its much more difficult if you drive it away and find stuff later.
Its easy to be excited about having the car back after driving around in the corsa and end up missing things that will become obvious after a few days of having the GTI back. Not teaching you to 'suck eggs' mate I just dont want you to have anymore hassle than youve already had!!
