Two ways to look at buying a former rental. Yes they probably get more maintenance than the average C but... they get waaay more abuse/use/miles. Do these two even out? Maybe.
Every time I see a rental C on the interstate they are blasting by me doing 75 or 80, every time! Were the V-10's not such a reliable, basically bullet proof motor a lot more of them would have turned to dust by now. The folks that heap that kind of abuse on the rental's engine surely treat the other systems as badly.
Count the number of large bodies atop the rentals at any Nascar event keeping in mind that most of them are not rated for more than one person on the roof, ever. AC, generators, plumbing and electrical systems tend to hold up well when properly operated often but abuse will surely shorten their working lives.
There are a lot of happy former rental C owners out there but given the number of quality privately owned C's that are available for not much more money I would not buy a rental. Lots of good advice above and more than a little misdemeanor thread drift on my part but something to think about. Good luck!
As always.... opinions and YMMV.
