2011 black Lexus es 350. I also bought the resistall enviroguard protection.
I have not had any problems other than ordinary car maintenance repairs. I did have a driver window issue a few years back, it wouldn't close correctly like it was off track and finally I couldn't get it to come up at all. The problem was with some piece that Lexus is aware of but has not resolved it to customer satisfaction. It could not be fixed without replacing the entire window. I took it to a window tint shop to replace it. Lexus dealership charged too much money. I do not know much about cars, so I cannot comment on performance and reliability. Comfort is what one would expect from a Lexus. Features are leather seats with heating and cooling controls, push button on driver and passenger side to open locked doors so key can be in your purse or pocket without removing it. Of course it is a keyless ignition. Also sunroof and button to slide it open all the way back, a backup sound alert, turn signal flashing lights, cargo net.
