hello, recently i purchased a 1999 Yamaha SR 125 off ebay for £450. and i need some advice as things seam to be dodgey, it was supposed to come on saturday however the owner couldn't find the V5 and so it has been delayed, i later found out (after he rang the DVLA) that no V5 had ever been issued and so this was the first one and therefore free, i have asked for the MOT certificates as i want proof that it is MOT'D. also when i tried to get a quote for the insurance using the registration plate the insurance company and comparison website stated that the registration plate and bike didnt exist, i tried doing a text check on the registration and again nothing, however upon going onto the DVLA website and putting in the registration the bike did pop up, same year and date of first registration and everything, i also checked the AskMID.com website to see if it was insured and it is. The owner did ask if i wanted to pay through paypal as it is more secure than cash but i already withdrew the money. also there is a new engine fitted to the bike from a previous owner so should the engine number match the v5? any help with this? im only 17 and thats a fair bit of my money im paying towards something that could be a lot of hassle. thanks
