There is a Vehicle out there that actually can drive on land, and then once in the water, converts to a boat capable of achieving about 7 knots (8 MPH), yet however, these vehicles had a bad tendency to roll over if you did not go very slow in a turn, and the metal used to make these vehicles was very corrosive prone, and would wear easily. In all honesty, these were not very popular, but they were in a sense, "Floating Cars".
Check out this site all about amphibious vehicles,

It was called an Amphicar, powered by Triumph Herald mechanics, it was capable of 75 mph on the road, and 7.5 mph on water. As already mentioned, they were rather unstable at speed, due to being rather high to keep the upper body out of the water. Here in the midlands UK, there is still one in reasonably regular use, any canal festival event, is likely to get a visit, and on water demo from it.
Regarding cars that can float, it used to be said that the original VW Beetle would float in water. Such was the efficiency of it's door seals etc.
Yes, they actually can float in water!
Cars don't float, they sink.
They float
Because they are not waterproof in the sense they will float.
Yes, provided you have the metal in a solid form which can be shaped so it will float, and a substance which it is liquid enough to float in at that temperature.
Any item that is lighter than the water will float on the surface of the water.
That depends what it's made of ! A metal one will sink, but a wooden or plastic one will float.
The car openings all need to be properly sealed to prevent water entry to the car body and then many cars will float. There are numerous holes and seams in the car body that are plugged and sealed but not sufficiently to prevent water entry.
