OK probably worrying over nothing, I've been told that there has been a fitting charge plus keying the locks which all takes time to do apparently.
2 new Alloy 12GSA Panniers with all the locks coded to the bike (and 2 spare lock barrels (coded) if I ever wanted the alloy topbox)
Price - well south of £500
You are being stiffed - they are taking your trousers down and spanking yer bum
However.................if you're a pushover
Why didn't you also try CW's at Dorchester and Bristol Motorrad for a price comparision when buying a new bike (no trad-in - you could have bought from anywhere in the UK) - they must think that Chrimbo has come early in Plymouth
