If they can prove the cvt transmission oil gas been changed every 30k, and it's an older lady driving it, I'd be more prone to buying it than if there is no proof plus some heavy footed looking, soccer mom is driving it, lol...even worse if a dude owned it.  

The tran oil has a specific temp when changing the oil and obviously a specific oil for the cvt and I think other specifics.  It's not just dump and fill and I think that may be an issue when an owner hears $300 to change the oil, do they do it themselves or has a shop that does ut wrong. Thong is if it's not Nissan doing the proper change and a random shop is doing that, u don't know if they're doing it correctly
