4 doors = sedan = family mans car or business geek or couldn't find a 2 dr....LOL That's not to say there aren't cool 4 doors out there ... that's just my take on the take of why they aren't popular.
There's a cool factor to any vintage or classic car just by virtue of it being a vintage or classic car. But the two vs four door thing isn't something that just pertains to older cars. How many times today do you see hopped-up two-door imports with the fart-can mufflers, light kits, turbo kits, fancy rims, and other paraphernalia racing around the same way we used to, and then comes along some guy in a four-door Accord or whatever they are, and it screams MOM'S GROCERY GETTER so loud it can be heard over the fart can on the back, and that guy is just the odd-man out? Even worse, the guy in the import sedan with the "rat rod" flat black paint job that screams MY MOM HANDED HER CAR DOWN TO ME BUT I HAVE NO MONEY FOR A GOOD PAINT JOB SO TO MAKE IT LOOK COOL I GOT AN EL CHEAPO FLAT BACK DEAL. And of course the worst of the worst, the guys who are struggling to look cool in an import sedan with different color body panels they took off a wrecked car, with the phony TYPE R racing badges on the back.
Now, in the interest of full disclosure, most of us have been in the sad position where we had to drive around the family car (my crosses to bear were a four-door Galaxy 500, four-door LTD, and a Monaco station wagon that proved even 440s can't make every car cool. And as an oh by the way, while I was driving around in the family trucksters, my Dad's "work" cars were a 1969 429 Marquis drop top, a Skylark, and two Mavericks... all two doors.
), but these cars were rarely destination cars for us. They cars driven out of necessity until we got a car that we liked, which is why I went from a Monaco wagon to a 73 Road Runner/GTX and not another station wagon.
Throughout automotive history, four-door cars were, and always will be, family cars regardless of if they were made in 1951, 1971, 2001, or 2021, and family cars are rarely built to be high-performance cruising vessels (with one exception, the recent Mercury Marauders). Anyone wanting proof should look at how NASCAR had to break its own rules to allow a never-produced two-door Charger onto the tracks. And why did they break those ever-so-sacred rules? Because having a four-door NASCAR racer would have made NASCAR the laughing stock of motorsports.
