Look it's probably not a big deal, but knowing how I treat rental/company cars I wouldn't want me driving an ex rental car I owned. If that makes any sense.Having said that every rental and company car I've driven have been naturally aspirated. If I had a turbo I would certainly do a few things differently. But would others? Would they flog it from cold? I don't know but probably. Would a private owner? Maybe, but less likely. In the end my 265 was a demo, and it was flawless. The engine, if looked after, is bullet proof. Warranty would probably cover you though if you're worried. You could ask the dealer too, but I don't know if they have to disclose who owned the car previously. If the deal was really good then you're not missing out IMHO. Also just make sure you treat it really well and get it serviced by a good mechanic and you'll be right. Then, enjoy!
