Mohtaram bradpit Sahib,
Well I've been careful enough to eliminate the 'selection bias' of the test drives I'm talking about. I live in Islamabad and roads here are as good as in Dubai or Texas. The 'bias' of poor road quality was eliminated by me when I selected smooth silky roads of Islamabad.
Talking about my C63 AMG. I've it in Michigan, USA where roads are worse than in Islamabad because of heavy snowing in Winters. Summers are mildly hot and Winters are extremely cold. This temperature variation tremendously damages roads and cracks them. The damage to roads is further aggravated by putting salt on the roads after snowing. Salt damages the road surface and has the ability to put large potholes in the roads. You will know that salt lowers the freezing temperature of water and is used by road managing authorities to thaw the snow so that it can be scraped clear by the ploughs. Authorities over there are always repairing roads. So my C63 AMG runs on roads in Michigan which are harsher than in Islamabad. That's why I prefer driving my Jeep Grand Cherokee on those rough roads and don't feel anything. I take out my C63 only when I find good driving conditions mainly in Summers when road repair is taken care of.
Believe you me, my C63 AMG will perform better in Islamabad than in Michigan because of better roads. The weather over there is very traumatic to the roads. Only 4X4s will perform better there.
When testing the ride quality of Corolla and Civic, I was careful enough to test them in Islamabad where roads are as good as in Europe, Dubai or Texas.
Cultus is a miserable car. Both build and ride quality is pathetic. When I was in my college years in the 80s, my mom bought me a zero-mile Suzuki FX to commute between home and college, 1985 model, and it has clocked more than 300,000 km. Its build quality is amazing and still going strong. It is better than Cultus. My sister has a Cultus which I drive occasionally and I've found the car pathetic. My FX drives better than it. Such is the appalling quality of today's Suzuki brand.
Regards.
