Rental, Dealer Used, CPO, Private Party or any other condition other than new must be evaluated on a case by case basis. My goodness I would have though that you folks on here would know that there are always exceptions to any rule. The car is used bottom line........ it matters not who or
what owned it, the car will tell the tail. Treat every used car the same no matter where or who she came from and you'll do fine.
Pictures tell you the model and maybe the color that's it. Put hands and eyes on it first; a lot of times this is enough to eliminate a ride from your list. Have YOUR mechanic or hire a pro to go through it. Do some homework, call Hyundai ask them to tell you about the car based on the
VIN. You will be surprised at the stuff you can learn. If serviced at a dealer call that service department and talk to them. Heck if you have concerns about a particular dealer or lot call some local body shops/repair shops in the area and ask them about the place its crazy the info you can gain and all info is good some not so useful, but it all goes toward a better understanding of who and what kind of car your dealing with.
Gems are everywhere but they are hard to find; if you limit your search bases on prejudices, hearsay and conjecture you make your search that much harder.
