Some will argue that they look better, while others will say they choose them because they are cheaper to buy and rarely have someone sitting in the back.
But for those who prefer the three-door hatchback typically more elegant than the five-door models, the choice is quickly reduced as manufacturers eliminate them from their ranges.
The last thing to swing the ax is Seat, which has dropped the slender Seat Leon SC from the showrooms with immediate effect, following the example of other car manufacturers.
The best things do not come in threes: Seat is the latest brand to get three-door models of its range, killing the pretty, but not so practical, Leon SC
The Leon SC is the sportiest version of the Leon standard sedan, with a coupe style thanks to two fewer doors and a sloping roofline.
It follows in a long line of elegant three-door hatchbacks and other car styles, but while they may seem more attractive than the more functional five-door variants, the car simply does not want them anymore.
According to AutoCar, sales of three-door models have plummeted in recent years, with motorists increasingly opting for more practical and versatile five-door versions, even when buying the smaller cars on offer.
The owner of Seat, the VW Group, has systematically eliminated three-door cars from the model alignments in recent months, and the León SC has been the latest victim of declining demand.
It follows the discontinuation of the Mii three-door city car, which cost around £ 1,000 less than the equivalent version of five doors when it was available.
Audi has eliminated the three-door models of the A3 line, which now offers five-door versions "Sportback", while Volkswagen has taken out of the sale Beetles, Poles, Ups and Scirocco three-door as part of the strategy.
Seat has already eliminated the Mii three-door dealers, and buyers prefer to pay more for a five-door version
Audi currently only sells a five-door A3 Sportback, with the three-door A3 Hatchback selected from the range
And while only three models of VW Group, Audi A1, VW Golf and Skoka CitiGo, are offered with three doors at this time, all will only be available with five doors when they are replaced by the next generation.
The German brand is not the only one that sacrifices three-door models.
Vauxhall has removed the painfully unpopular three-door GTC Astra from the showrooms, and Kia plans to add two additional doors to the next Proceed when it launches later this year.
Range Rover, which would sell a SV £ 240,000 coupe later this year, is the most expensive model in history, has also trimmed the three-door Evoque from its lineup.
The painfully unpopular Vauxhall GTC, a three-door Astra, was discontinued a while ago
The three-door Range Rover Evoque, which was used extensively to market its sleek look when it was originally launched, has been removed, and buyers are moving in droves for the less attractive, but more useful, five-door version.
