It would depend on how much better the self parking is on the Lexus. Lexus is only the 1st Generation which is not good. Since this self-parking system doesn't work, there is no reason to buy a Lexus and I hope they understand why they are not selling too well.

Audi would probably have the best self parking system when it comes out. Lexus made the system too complicated where 3 grown men couldn't use it. Also they need to add a feature where the car will not attempt to park in impossible places and to put itself on drive itself and drive into the parking space.
