Just for the record, my repair was done under warranty (and with great reluctance) and I had to take my bike back 3 (three) times for them to get it right. Fair do, M&S finally got it right but for servicing I'll be looking to Ducati Glasgow I think.
Oh, and M&S are well known for not offering test rides, me and a mate caused a real fuss one weekend about it in the showroom! They've lost big money that way from personal experience alone. I eventually bought mine without ever riding it, but only because I couldn't leave the place without it!
