Well... To give any comments, I had to read the complete thread from beginning till end... And I have reached to a conclusion...
I owned a GLi 2009. Recently sold it just because of Black Colour. The problems which have been mentioned here are really new for me after driving my car for round about 8 months. The only problem I faced was the fading of panel which I changed for 7k only from Rwp. The drive is awesome even on CNG (but for that u need to get it installed from an expert along with Advancer), although u cant compare it with CiViC Reborn...
The brakes were very good and ABS saved me a couple of times from crashing into other cars/people going on road. Though I am more inclined towards Honda but I really liked this model of Toyota. Though it still needs improvement but I still prefer Corolla over other 1300 cc cars. I have never drove Altis so I cant compare it with other 1800cc cars.
I never experienced Axle problems. Drive is smooth and good. No steering problems, rather smooth and good. The only thing is that its not as tough as the previous models but still tougher than CiViC...
I dont grade XLi good because of very limited options. No offence please. But this was how i feel. 
Shall upload the pics of my car as soon as I get time.
