Car Data Check

Well it's a bit late now TBH. If you had asked them specifically if it had been declared a write off, they'd have to tell you but they don't have to volunteer the information so as you didn't and they didn't tell you, if it subsequently turns out to have been a write off, you've no comeback on that. There's no point doing a HPI check for finance because they'll have done it when they bought it and likewise to see if it was stolen. If it subsequently turns out it was stolen and is a ringer, you can come back to them for selling a car that wasn't theirs anyway but make sure you keep the receipt. Mileages can be fiddled that much as to make a check on them basically worthless, especially on a car under 3 years old which won't have had an MOT.
