Do car dealerships have new cars?

Yes the car dealerships can have the new cars also only the thing is that you have to demand for the new one from your side.

There are two types of dealerships. There are new car dealers and used car dealers. New car dealers are almost always a dealer for a certain brand (it may be a Chevrolet dealership, for instance) and will have both new and used cars. Used car dealers are normally (but not always) a small independent dealer, and will only have used cars.
