Cars in the 1960s were just a work of art like the Aston Martin DB5, the jaguar e-type. Cars in the 1960s were not very good in engineering though because their electrics were poor, their cooling system were awful, and the price of the 60s cars today are incredibly expensive.
4X4 cars are the most unreliable cars ever built like the BMW X5, the Range Rover, the Volvo XC90, the Audi Q7 etc. 4X4 are also heavy on their fuel. Some 4X4s are incredibly uncomfortable, but the range rover though is the only 4X4 that is comfortable.
American were and always be appauling because they are badly made from very very cheap materials like wheely bin which is used for the wings of the Cadillac CTS. Terrible plastics for the corvettes as well. American cars are also incredibly volga, they are way too wide for the roads here in Britian and they are only avaible with left hand drive.
When British Leyland was formed in 1968 everyone expected them to be an absolute nightmare because all the cars that they ever made were unreliable, made badly, terrible electrics in the cars as well.
