I booked my Coupe Turbo in for a Cambelt & water pump change in January,
goes on saturday a whole three and a bit weeks after booking the job and guess what!.........
"Oh I'm sorry sir but one of the tensioners hasn't come in!"
Needless to say I was massively annoyed and only held my anger enough to book the work for the week after!
So if you want to make sure your parts are in on time may I suggest giving vauxhall a months margin to get parts!!!!!!!!!!!
