When I sold my T6 recently it was a 2019 conversion with 3,500 miles on it. The lack of use was purely down to difficult family circumstances. Like all of us on here I looked after it diligently keeping things like the battery charged up, annual has checks etc. It had a full VW service history, cam belt changed at 4 years (as it was then) and I kept a full set of documentation with it (like I do for all my vehicles).
It sold in about a week!
