I was using Wagon R VXR since March 2014 and now bought Cultus VXR, following are the good things in Cultus if we compare both Wagon R VXR
1- Cultus is wider then Wagon R, Cultus 1600 mm and Wagon R is 1475 mm wide
2- Overall length of both the cars are same but the wheelbase of Cultus is little longer then Wagon R.
3- Gear position and gear ratios of Cultus is better then Wagon R
4 - Seats are more wider and comfortable
5- Visibility is better due to thin A pillars as compared to Wagon R
6- Road grip is better as well along with 14 inch rims
Other then this you will be getting Bluetooth audio/ call, 4 power windows, a bigger boot, central locking, key less entry, 5 bottle holders, adjustable steering along with internally adjustable side view mirrors but the quality of door panels is not good, I hope it helps you to take a good decision.
