Mick - When you say he doubts he worries this type of belief is ill-founded. Assuming that (in this case) because he's got 3000 custies he can afford to wear a high fuel bill, well he can't, as he indicates in his reply to me. If he has 300 or 3000 custies he'd have to watch the pennies just the same - Soapies variable costs will increase exponentially the more custies he has.
In his case, his Land Rover branding is worth the cost of the extra fuel he spends in running them instead of vans. He's a businessman and if he felt he would make an appreciable saving in switching back to vans (when fuel, branding, maintenance was taken into account) i'm guessing he'd switch back. He doesn't because it's worth sticking with the Landies.
I don't mean to speak for you Soapy. Let me know if I have an of this wrong.
