Everyone in UK got sent out the replacement red v5 so if he hasn't got it then who has? The cars registered in someone else's name, so who's saying the cars even his to sell? All in all I'd say to him if he can get a red log book from dvla then you will definitely buy it, no ones gonna buy an Rs ford without it so it shouldn't sell in the meantime. you'll soon find out if he's a scammer when u never hear from him again! If u do hear from him and he's got it then happy days
