Most of the points that have been listed as advantages for sedans are technically true, but are just not applicable in everyday life (read home-office-home commutes, shopping trips and weekend short trips). Let's face it, 90% of the (non-transport) cars spend more than 90% of their running lives in the city, battling stop-n-go traffic.
For example, I have not seen anyone taking full advantage of their cars' performance or cornering abilities on an everyday basis (except BPO and call-center drivers, who take undue advantage of it

).
Similarly, ride quality does not play a significant role for everyday city commuting. In fact, SUVs score here because of their higher GC, which helps in absorbing all those wicked potholes and illegal "car-breakers" in your stride. Plus, they are spacious, which means 3 people can comfortably sit in the 2nd row, unlike most sedans. Again, when the 2nd row is fully occupied in a sedan (read 3 people), the rear suspension is invariably bogged down, severely affecting the vehicles ride quality. This also leads to more scraping on potholes and car-breakers. This never happens in an SUV, unless it's suspension has gone kaput.
Depth of engineering is a very very subjective issue, and in this debate, also a non-issue. As someone rightly said, lots of bells and whistles in a car do not necessarily mean advanced technology. In my view, in city traffic, it really doesn't matter whether a certain car has drum brakes or disc brakes, as long as they do their job well, i.e. stopping the car within a certain safe distance.
Ease of maneuverability is again a subjective issue. It really depends on the dimensions and turning radius of both vehicles. The SUVs will definitely be harder to maneuver than most smaller sedans, but easier to maneuver than most of the bigger sedans that we have. As for parking, it is true that an SUV needs more space, but the trouble can be mitigated by careful pre-planning (identifying and memorizing parking zones before reaching the destination). This requires a bit of practice.
The points I feel that really highlight the advantages of sedans are:
1. Fuel Efficiency.
2. Cost.
3. Parking slot size (at home).
4. Petrol (but diesel engines are getting better 'n' better everyday).
5. Choices (these will get better as young India's purchasing power gets better).
As for SUVs, advantages like
1. Ability to handle rough roads.
2. High perched driving position.
3. Space.
4. Hauling Capacity.
5. Muscle.
are real positives that make it a "must-have" for our maddening city roads and insane traffic.
A couple of months ago, in my quest for the middle path of this very debate, I finally settled on the (used) Tata Sierra Turbo. I am a die-hard Sierra fan, but I also realized that this car comes closest to what I would look for in a "mini-SUV". When I suggested this to my family, they asked "Why not Safari?" I said I didn't want the extra seats and added length, which would make it a pain to drive in the city.
Now, I have been driving the MS WagonR around for 6 years, and that car fulfils most of my practical requirements, including hauling huge loads (thanks to the rear folding split seats). But what I didn't like was it's low GC, thanks to the famed pot-holes and "car-breakers" in Pune, not to mention the "work-in-progress-till-eternity" roads. The sheer lack of road presence was what really got to me. The auto-drivers were ever-willing to rub shoulders with me, and cyclists and bikers cut across like I just didn't exist.
All that changed the day I set out in my Sierra. Suddenly, I could see the traffic for miles ahead. All those sedans/hatches looked like herds of sheep, and I could see right above them, across their roofs. Pot-holes and "car-breakers" could be conveniently ignored, like they didn't exist. Auto-drivers shuddered in fear, cyclists and bikers began to part like the Red Sea before Moses. I was the king of the road!!!
That apart, the humongous sofa-like seats are a treat to sit "in" (not "on"). Also, the smaller dimensions (relative to other SUVs) make driving and parking easier.
In short, it is an SUV, minus all the negatives associated with an SUV.
I really feel it is time to revive the Tata Sierra, and/or introduce the Ford Bronco 2 in the Indian market. I am sure they will sell like hot cakes.
