Chevrolet Spark from GM

I regret too for selecting Chevrolet Spark from GM. I also availed their Celebration Offer and they promised the samething that they would take max of 3 weeks but it is already 3 months over and all I am getting is excuses. I got an apology letter from GM, Gurgaon and they have promised to deliver the car by Jan 2008. I have already paid 3 of my dues to the finance. GM really sucks for breaking their promises and I am started to worry of further services with GM.
I was very curious that I would get my car for Diwali’07 but now it looks like I will get it only for next Diwali’08.
Stupid GM Management !!!
