I disagree, at 5 years old an SS with low kM in great condition will more than likely pull more buyers than higher kM with more wear in an SS Thunder. The only difference from memory was 19" wheels over 18" (probably changed by now anyway), Satnav (old tech 5 years later) and some leather on the seat sides. Plus you'd tend to buy what is near to you. HQ would have been the same, plus back then a Sandman van was often far dearer to insure than a Belmont van.
