Q. I am buying A4 .Should I go for petrol or diesel .My running is approx 30 km per day.Also is black colour ok ?

Its an Audi and hence it better be a petrol ! OK jokes apart , for your kind of usage ( about 10, 000 km per annum ) there will hardly be any big difference in running costs. But for sure the cabin noise / vibration etc on a diesel variant will be high ( relative to petrol ) . Sure the diesel delivers a slightly better torque but I am sure if you run your petrol in the Sport mode you will hardly notice the difference. And colour - well let me be honest. I have had more white cars but when it comes to class , nothing comes near a black vehicle. Just to ask a simple question - Have you ever seen a Presedential Limousine that is white ? Ha ha !! Anyway for its looks the black is tough to maintain in top shape - you have to either give a ceramic coating that will last 3 to 5 years ( about 45K will be the damage ) or do a shampoo wash once every two weeks or monthly. You can do this at home with a 3-M kit and the results are astounding !1

PETROL IS ALWAYS BEST OPTION IF U LIVE IN INDIA AND I PREFER WHITE COLOUR AS IT LOOK MORE STYLIST

Please go for Diesel as Petrol is not powerful. Black colour is OK but you have to maintain it well as it catches dust easily.
