A similar situation with my brothers Type R... He bought it from an auction then found out the chassis number had been tampered with. He called the SVS out (Stolen Vehicle Squad) who checked the car over fully and said it's fine and was once before stolen recovered. He got it on the road and got shit off the police a few times, but he told them the full story each time. Then the DVLA wanted to see it and they sent us a letter, they told him to take the car down which he did but for some reason they said they couldn't check it on the day. By this time, which was 6 months later, my brother was bored of Vtec and wanted a diesel so the car was up for sale. Someone came to view the car, we told them absolutely every detail on it and the buyer was happy with the price he was paying for it. He left a deposit and was due to collect 5 days later, however the police came to our house the day before he was supposed to collect it. It felt like they had nothing better to do, no matter how many times my brother showed them the SVS report, they would come back nagging. This time the officer said he needs to take it to the DVLA once more, to which my brother said no chance, as they are a waste of time. He said he would be in touch the next morning and if the car was sold he was going to arrest my brother for handling stolen goods. The next day he waited until 3pm no sign of the police and then the new owner came to collect the car. My brother left his number with him and said to call him if the police said anything at all. Officer comes knocking on our door once again the next day, and my brother told him the cars sold. He was being an arrogant twat as he was quite shocked my brother didn't listen to him (the law doesn't say he should have listened) but there was nothing he could do. He threatened my brother that he will be seeing him in court as he didn't listen to him and that he can be in prison soon for handling stolen goods. Completely full of shit. 6 months later and we have heard nothing from the previous owner or the damn police.
