I would be wary in using a car bubble (of the type you describe) for
prolonged periods. If used on a new car, then you may have a problem
with plasticizers volatilizing and settling all over the car,
particularly if the temperature inside the bubble gets hot (eg
exposure to sunlight). With old (not restored) cars, you can get an
increase in corrosive gases resulting from the degradation of some
plastics and rubbers. The bubble should work well if you attach a
dehumidifier to it and pumped fresh, filtered, dry air into it,
providing that you allow air to escape, that way you reduce the
possibility of  concentrating plastizer and/or degradation gases.
