There is minimal choice in the sedan market today, and your best options are the Skoda Slavia and Volkswagen Virtus, which have strong petrol engines, excellent ride and handling and a comfortable cabin.
They are ideal for your mix of city and highway drives and come with a high level of safety, too. If you are a regular driver and don’t want extra performance, then the 1.0 versions paired to the 6-speed automatic will work well for you.
Both the Slavia and Virtus are identical except for the design and a few feature differences across the variants. So the one to choose depends on your comfort with the dealer, the design, your affinity with the brand and the best deals you get.
