When I was young a 4dr was an "old persons" car and mine had to be a coupe or convertible. At about 50 years of age I sold my 50 Ford Convertible to a country singer named Eddie Rabbit and was without a car to go on a cruise I liked. Saw a 37 Buick sedan at the Arlington, Texas swap meet for a very reasonable price so bought it to go on the cruise with intent of selling it when I returned. That was 30 years ago and now I will not get in a car that the back of the front seat has to tilt forward. With a sedan you have a trunk plus a secure storage area that is easy to access and a place where friends can get in or out without disturbing the front passenger. Sometimes age does make one smarter. PS; if looks mattered to me I'd have all the mirrors in the house removed.
When my son wanted a car, first off he did not get his own. He wanted a 2 door and I explained to him when toting his friends around it is raining it is more practical to have a four-door rather than standing out in the rain to let him in. BTW I asked him why he wanted a car when he had 2 very attractive girls bringing home every day.
New cars have no styling to speak of, so who cares if it is a 4 door. Cars made prior to WWII have so much style that it doesn't matter if one has 4 doors. The cars in between, why, they need to be 2 doors. That's just not debatable, unless you're old.
I subscribe to "Hemmings Classic Car" magazine. One thing I like about them is they feature 4 door sedans and other "plain jane" cars that people either have restored or nice originals. Their point being that everyone is after the convertibles and two door hardtops and the 4 doors are mostly ignored, when the reality is there were actually more of those cars on the road back in the day.
