Just bought a T6 SWB on a 65 plate 47k miles. It will be built to a high standard and with quality components, Crash tested Bed, Double seat swivel base and Poptop roof, Dometic appliances, No MDF or Chipboard furniture, No cheap crap or cut corners £22500 + the Vodka.
I can go as lairy or as mild as you want on the colour scheme, (Bright colours and glosses = more wow factor)
Dont bother trying to get CAP guide on these things, buyers are totally lead by their hearts, I've never chipped on the price of done vans or a conversion. £29995 on a pitch at the start of summer is realistic
