I love the car I got here, but the experience is a bit bitter as it recently turned out.
When purchasing the car, the sales person assured me that the car has brand new tires, and I didn't check. A year later (10k miles), tires are completely worn off.
Apparently, the tires haven't been changed since the car was manufactured (I bought it CPO).
And, like nothing happened, during one year maintenance, they wanted to replace them for 2 thousand dollars, twice the normal price.

It would've been okay for me to buy the car with almost worn off tires, but at least they should've told me. It's quite dangerous at least.

These sales guys are liars. Just keep in mind.
