Good luck Jaime 
Have you checked the screen for chips bigger than 10mm?
Getting my new screen for the merc thurs.....done all the other jobs as well....bet i get charged again for MOT.....its been slightly longer than 24hrs 
Yes, a large chip behind mirror...
I would have thought that would be ok.....as its not in line of vision....depends how picky the examiner is i guess? :-/
Talking about windscreens....windscreen blokey phoned me today....saying there are two different for your merc....which one do you want?.....Both screens have slight green tint all over....but you can have a grey sunshade band (the bit at the top) or a green one ....i said i dont care...whichever one you have or can get the quickest....windscreen blokey said ....ohhh well i'll order the grey sunshade band then....their more expensive

I dont care really coz insurance is paying except the first £50.....but just goes to show!
