Gulp!!! Glad you mentioned that Highwayman, I might have lost my roof box on the M20. What on earth are the roof bars there for then?
I bought my roof box in France a few years ago. I was in a Hypermarket in Boulogne and they had just upgraded their stock of boxes to super duper mettalic paint jobbies. There was a lonely plain black 50kg box on the top shelf with no price on it. I asked the assistant how much and was told 300 francs. ---That was 30 quid!!!! Yep, that'll do for me!
I'm not tight --- I'm just careful with money!
