the joke is that its the ‘vw scene tax’ you are paying
there are two sets of vw price, sensible and what idiots think their van is worth when they put a stupid stick family sticker on, some ghastly wheels and heaven forbid a lei.
best thing to do is just look at loads then make your mind up. its easy enough to buy a basic van and have windows put in, lining and flooring are all totally DIY do-able and many companies sell excellent RR beds (i bought a spacesaver one from jds metaltech in sheffield and would totally recomend them).
personally i sold my T5 that i had for 7 or so years and bought a ’71 microbus for a toy and a berlingo multispace for day to day.
the t5 i had converted myself and easily got my cash back, but i sold because it was a utter expensive pain in the bum that was always throwing up electrical and mechanical niggles. do a search of the t5 forums, you will always see the same ‘what does this dash light mean’ threads.
