For me there are many levels of 'special' cars. One level is the great cars through history, Mercedes SL300, Ferrari F40, Mclaren F1 and the likes. Another level is the engineering in cars like the koenigseggs gemera that go from 0-200kph faster than many cars do 0-100kph. The carbonfiber wheels are hand made. A Swede is handlaying layers of carbon fibers cloth, before adding resin and then curing process. The modern mclarens are also fascinating engineering wise.
The last level are cars that it's possible for me to own, right now I have a BMW. don't know what I'll get next. Some porches are nice, maybe my priorities change I'll just get a Polestar 2 or something. Anyways I like BMWs, maybe i'll get an old 3 series like an E92 to have as a summer car.
