I have agreed a sale on my van. Buyer has asked for the chassis number and the reg no. I assume there's no reason I should not release them? I read so many scare stories of scams and I am just so green when it comes to the issue of buying and selling cars I'd really just be grateful for what I need to look out for. At least the buyer has not asked if I will ship it to Guatemala and he'll pay me £5000 more than I advertised it for...!
