Most smooth and flawless Luxury Car among 3

I have all 3 premium Sedans BMW, Mercedes & Audi. The new Audi A4 has a high class of refinement in Engine and Gear Box. Interior trims are on par with the Mercedes S Class. Noise levels are very less. Do test drive all the three cars at least three times with different dealers, then you will be able to appreciate the differences. Acceleration of A4 Diesel is more refined, effortless and quick. The A4 has a torque of 400 Nm @ 3000 RPM while that of the BMW is 400 Nm@4000 RPM. Don't waste your time and money on Mercedes as it sucks with frequent electronic defects due to more than 40% local supplies. New Q3 2019 is also awaited eagerly. Maintenance of Audi is generally half the cost of others. You will enjoy best when you negotiate hard as dealerships provide upto 8-9 lacs discount. Its a part of very large group of Volkswagen, Skoda, Porsche group. Therefore you can afford to reduce costs of ownership and maintenance.
