Cost of plating a 7.5t please

[MyBoyChe]

Can someone explain to me please the difference in costing between a 3.5 and a 7.5 in terms of plating and road tax (and anything else Ive forgotten) Am a complete lorry novice and it seems I can buy a decent 7.5 for the same as a 3.5. Im quite old so can drive the non HGV ones on my normal licence but not sure how much more in terms of running costs. Thanks guys

I think it's £93 for an LGV mot; I think my last tax was £165. But then I've got so much money I take no notice of these things
