I would probably go to a new car dealership and try my luck there. My son got a nice 2017 Golf from GoldStar, in Carp, . It was in 2018 and he got is for 17,500. 30k, rental return (which doesn't scare me). Drives beautifully. However, a year and a bit into it, the bottom door sill started to peel. Hmm. Went to dealer for a warranty repair and they said that the car had been in some sort of accident and it was repainted poorly. I didn't catch it when looking at it, as the paint match looked quite good, but they figured something out , even measuring the paint thickness so the evidence is irrefutable! Waddaya gonna do?
Car had a clean CarFax report because Hertz clearly fixed the door and didn't file a clam, so don't be fooled by CarFax reports. get the car checked out.
Rental returns, I have been through a couple and only brakes really take a beating
