Good post which will be very useful for those with Kombis which can weigh in under the magic 2040kg unladen weight figure . Unfortunately my 6.1 SWB 199 4M comes in at 2252 Mass in Service so even with driver / fuel adjustment c 130/140kg I'm confined to the 50/60/70 rules. The whole classification / dual purpose / speed limit laws need a complete overhaul given need to have to explain the rules to the issuer of tickets to enable a wrongful fine to be cancelled. Plus in my case with a virtually new 6.1 4M T32 Kombi with big brakes and latest safety features, I am restricted to 10mph less than for example a 10 year old T5 Kombi with possibly several hundred thousand miles on the clock. Mind you motorways are ok except for fact there are none down here in Cornwall . I was fully aware of all of this when I ordered the van mind you so can't complain
