A Star or Z star???

I found most of the review on various sites. total waste ,un real , mis leading except few points , why i m saying this bcoz last month only i purchased my 3rd car as A star , i m hving GM's Aveo( for last 2 yrs), santro for last (11 yrs) , when i drove A star on highway at a speed of 90km/hr it starts vibrating and when it crosses 100, the whole dash board looks like a vibrator with sounds coming from each and every corner...highly disappointing performance on highway...also i can bet on my santro which is 11 yrs old is still much smooth/refined on highway with a speed of 100 plus...which is total missing in Brand new so called A star...i strongly reccommend maruti guys to rename it as Z Star (Mean ZERO Star)...with Maruti u CAN NOT expect much on quality...they only play pricing game and hv build good service network in last 20 yrs and that was only bcoz competition was not there...but now we can feel the maruti's downfall after entrance of europian

player like VW, GM ..Hyundai is a Big big threat to Maruti...Guys for sure u will not hv easy time ahead ( the way u ruled india car mkt for last 20 yrs..thats  bcoz there was no competition ).
