I have a BendPak mid-rise scissor lift, MDS-6LP, in our current garage and we had one in our last garage. Both installed by me and both in-ground for a flush finish to the floor when down.
We have had our '16 Audi S3, '17 Macan GTS, '10 C4S Carrera, '15 911 Turbo S, '71 914-6, '18 Honda Ridgeline and '17 Audi SQ5 on them with no issues. The key is to check the widths of all of them to make sure you mount the lift ramps a correct distance apart so all cars are accommodated. I always bolt lifts down. Good luck.
