Has anyone attempted to install a power driver side rear door or ultrasonic rear park assist on a vehicle that did not come with it from the factory?

I was thinking of attempting this in my spare time...

What, nobody wants to add two of the most troublesome options to their car?

Ha, ha.....so tell me Paul, 4 years later, were you successful?

Are you freakin' kidding me? The cost of all the parts for either option would be unreal, never mind the expertise involved......might as well just take a hammer and bang your toenails for excitement......
