I bought a new car.

I drove my car to work this morning.

I rented a saloon car for our road trip.

I booked a ticket for the sleeping car.

I used to play with slot cars when I was a kid.

The squad car drove down the street with its lights flashing.

The armored car rolled down the street, ready to protect its occupants.

I had a drink at the bar car on the train.

I parked my car in the car park.

I had dinner in the dining car on the train.
