I wonder why anyone would want power lift for trunk? I had it and after few iterations found it extremely useless. Here's why: I can open and close my trunk 10 to 15 times faster than the system. Usually, I need to put something in quickly and move out or take something out, quickly. The only possible justification I saw is when there's that foot underneath and the sensor triggers a trunk release when my own hands are full of stuff. Whether I'd spend $300+ on just because of that which happens once a quarter (hands full) I can't truly justify.
The next issue I found is when my trunk's full. The lift gate when closing even if it finds a little obstruction swings right back. My problem is I realized it only AFTER I started moving. Whereas with manual, I can bang the darn this close.
Trust me - the novelty quickly wears out!
