Mercedes-Benz A-Class Limousine price in Kolkata

All the cars you have shortlisted, being sedans, have similar ground clearance, and for all practical purposes, the Audi A4 is no worse off than the other two. In fact, in our testing, it was the Mercedes-Benz A-Class limousine that required the most care over speed breakers. If ground clearance is a high priority, consider an SUV like the Mercedes GLA, Audi Q3 or BMW X1. 

However, if you want to stick with a sedan, the Audi A4 is the most value for money. Not only is it larger and more spacious than the others, it also has the most comfortable suspension. 

What's more, its 190hp, 2.0-litre turbo petrol is larger and more powerful than the engines on offer in the 2 Series and A-Class, and the most refined among them too. 

Given your budget, however, you could even consider an Audi A6; check if your local Audi dealer is offering any discounts, and it could fit within the outer limits of your budget.
