Well done with the Van brilliant job, a nice van for two people, would I be correct in thinking that your in the cabinet business, you certainly could go into the van conversion as a sideline if not more.
Re, valuation
I take it you haven't got it registered as you have done it from scratch in that process you have to bring it to a motor engineer that is registered for the purpose and send his completed form and a bunch of photos of the van to Wexford where they will put a valuation on it and unfortunately charge you 13% of that figure for all the good work,
but it will do a few things for you.It will give you a base value to work with, give you a final cost of the whole project and how much you want to make if you sell it.
You may also have to send photos for to get it insured they will want to see the likes of the gas bottle arrangement complete with TWO straps.
Get rid of the race van transfer they don't insure race vans.
The very best of luck in your travels.
