do not buy a high miler, as the there are many low milers out there at similar prices.
check the moonroof (sunroof) is in full working order, check all the door are in sync to the remote and check the A/C by turning on its coolest setting and on highest power if it goes very cold fine but if not leave the car alone if you look at the idle needle it will drop slightly when you turn on A/C this shows the motor is running
