first van buying private

Hi! Im kind of plaging this site with questions sorry!

Im looking for pros and cons of buying a van privately

the van we are really keen on is a 4hr car journey which we are willing to do but really weary!!

So i'm going to ask as many questions first and research as much as i can.

Also the chap is happy to email me documents to check before travel as well.

thanks for your time cc35
