I think the variant you drove had issue with tyre pressure. I also experienced the car, found it exact equal to the previous generations of corolla in terms of suspension, same classic Corolla suspension, there is no change at all.
However, like i have pointed out in my previous posts, 1.3 variant was not as powerful as 1.5 being CVT. If you are buying an automatic variant, buy the 1.5 trim.
Manual walay ankhein bund ker kay 1.3 variant khareed lain, 1.5 lenay ki ghalti na kerain.
The ugrades you get in Ativ X variant are worth it. Keyless entry, Push Start, Screen, Back Camers, Sports & Eco Driving modes, 6 Speakers, Chrome door Handles, a better gear lever and then again a bigger engine.
