Over the last 20 years I have had 3 campervans and all have been Volkswagons, reliable and have a good resale value.
My first van was a type 3 hightop 2 ltr petrol with 67k on the clock when I bought it.
Had it for 10 years and got £5000 for it in part ex, then bought a beautiful type 4 2.5 turbo diesel for £22000 part exed that for VW coachbuilt that I have now, beautiful motor its only got 22k on the clock, will last me a lifetime.
The Brazilian look alike vans look ok but dont have the VW quality, they have upgraded brakes and heating, dont know what they are like to drive though, apart from that they are too small.
The motorhome I have now is roomy, comfortable, dual heating gas and electric, a proper toilet and a really good galley the bed is about 6' square, all in all a very nice van.
