I got my Vespa MOT'd a bit early in time for Rotterdam at V Twin motorcycles in Horwich. 01204 696668. I've used them for the past few years and recommend them 'cos they understand that your scooter is a 50 year old design. As long as it's safe they'll pass it, I've found.
£25 of your hard earned it'll cost you.
In talking about the Rotterdam trip the boss, Ste, said he'd been breathalysed when he got off the ferry. They don't nick you, they tell you not to go anywhere until you've sobered up!
(But I wouldn't count on that meself.)
Another thing he said was that you lose an hour when you go onto continental time so that's one hour less to get over the night before.
