To much mate, tell you what I will bung you £1000 as a favour for it! Only kidding obviously! I’ve been looking at loads of secondhand turbos, think the problem you may face is if your spending say £500 on a used turbo people feel semi comfortable about it and hope the seller is being honest. When your spending near 2k people worry more that it could be a dud. If you have graphs related to the motor showing it only running x amount of boost, producing x amount of BHP it may help convince people it’s not been battered. It clearly looks in good condition in general but that doesn’t always guarantee it’s a good one. Maybe some more info as to why your changing etc may help. You say bought in May, assuming this year 3k miles in that time is a lot really which some people may also question. Do you have the original bill of sale? A copy of that would also help I’m guessing. Just my thoughts.
