So I have had some large cars, but my 95 Fleetwood was the largest, and at 225" long was one of the largest sedans ever made.
Here it is next to a Smart car. This is circa 2008.
Keep in mind my car is pulled way up over the front curb in this pic, and its further away from the camera, the pic doesnt do it justice haha.
The lady who owned the smart saw me taking the pic as she came out of the store and said wow that is a huge car you have and I said "No, it's just your smart car is so tiny" we both laughed.
