country cars type car style transmission pimping culture masculinity boost (out of 10) (very subjective opinion)
USA Depends disproportionately mostly saloons Automatic extreme 5 for the sake of pimping
on the power of the engine and trucks
hence- Muscle cars
Japan Very technical: Great Various, Manual, DSG extreme 8.5
Aerodynamics, chassis, torque, best are Hatchbacks
Credit: attention to fine details
Germany Same as Japan same as japan + sexy 70% Manual Limited 9.0
But also have Mercedes which 30% auto
is a muscle car and mostly Auto
(Big plus: have Buggatti Veron)
Italy Home of the world's best super cars Super sexy Manual, Flappy, Limited 10
Auto, DSG.....
UK Like to have everything but makes Various Same as Germany Limited 6
little. Otherwise same as Germany best are Hatchbacks
Except Lotus, Caterham, Maclaren, Aston Martin, Rolls Royce, Jaguar, Land Rover are not hatchbacks are all made in the UK (owned by foreign companies) but, are defiantly not hatchbacks. As for the lack of pimping culture in the UK well it did use to be huge in the 90s but has kind of died off. Pimped cars are now seen as an embarrassment and if your friend happens to have a pimped car you would rather get a Taxi then be seen dead in his car.
I'd consider the USAs muscle cars and trucks to be far manlier and macho than any of the others except for their prestige brands. They are built specifically for men whilst non of the others are. Muscle cars and Trucks are affordable by the average blue collar worker whilst a Ferrari is not.
Also don't forget that whilst Italy has brands like Ferrari and Lambo and Germany has Bugatti the rest of the cars are very mundane if not puny in Italy you have Fiat, Lancia and Alfa (Whilst Top gear always big up the Alfa you have to realise that they are just shitty cars) and Germany you have BMW, Mercedes, Audi and Volkswagen. Of course they produce one or two exciting versions of these but the majority that are sold are snoozefests and most certainly not manly man cars.
Also you missed out Australia from your list which has a massive car culture. Most of their cars are Japanese but they also have Holden (a subsidiary of GM) that builds some crazy muscle cars and muscle trucks exclusively for the Aussie market.
