Everyone has its own experience, knowledge and taste. If u are a car junkie with knowledge and patience and some money in your pocket. Buy a Mercedes but before buying such cars always keep in mind to buy the cars in mint condition and not the ones abused and altered by our mechanics just because the previous owner doesn't had money and he used to go to any lallu mechanic instead of taking the car to the designated workshops.
Every car has its own feel and driving pleasure. Jo cars saree world mai lead ker rahee hai unko yahan log kehtey hain k bekaar aur expensive hain. Even ppl compare Honda being expensive over toyota.
So if u wanna show off and enjoy the old German ride...buy a merc in pristine condition. select the designated mechanic/workshops who now the technical of the car for routine maintenance, so u don't end up overspending and getting ur car ruined.
Otherwise, buy a normal Japanese car.
