It is always interesting to watch and see how World Rally Teams support their cars at pit stops - ususally you'll see the cars up on four jack stands and a garage jack or two under the diffs.
Also interesting to watch how manufacturers raise road cars when testing at the Nurburgring or winter tire testing. The Ring has garage lifts for raising. Pictures I've seen of Porsche doing winter tire test near the Artic Circle show one corner of the car raised with a hugh floor jack. I also saw pictures of a Ferrari Challenge cars lifted on one side at the center of the wheelbase by a hugh floor jack.

I have seen in Mercedes dealerships, on a garage lift, techs use inner structure inboard of the jack pads at the front below the front firewall to support a road car and in the back the rear jack pad points. tech said he did this for stability.

I've seen auto body repair shops use all kinds of items and methods for lifting and supporting cars while in storage.

I haven't seen any pictures of a manufacturer supporting a modern road car with four floor jack stands. And the most recent picture of a Ferrari F430 Challenge car seems to show an on board pneumatic three point lift system - but I have a feeling this may have been a special set-up for display.
