at this rate it won't be until 2009 till everything is stable enough for an sc owner to jump to a tc. I woudn't wanna go through another set of years before things leveled out. First year with the balt nothing second year finally some decent upgrades 3rd year things are great ... then it was dropped. At least that gives time to save money.
My bad. I bow to your superiority.

I have to appologize here. I read your first post completely wrong. In my inability to read the English language, your first post came out (to me anyway) as saying "at this rate it won't be until 2009 before everyone is stable enough for an sc owner to jump to a tc." Hence my reference to the financial situation of SS/SC owners.
My bad. I bow to your superiority.

OniMirage is right about the aftermarket , i lurked on these boards for 8-9 months before buying my ss/sc , then i joined . It was almost the exact same speculation about stage kits and tuning for the SC back then as it is now for the TC .

Your kidding me right? I bought the cobalt the first ******* year it came out there was NOTHING for this car that was quality enough to use. torque dampeners twisted, intakes had fit issues, mounts didn't help wheel hop, piggyback systems caused drivability issues. Going into the second year there were stage kits, decent intakes that corrected fit issues, some mods caused cels or limp mode, HPT made a great appearance and helped alot, GM's own kits had an update to correct drivability issues. Going into the 3rd now and there are lots of good mods and upgrades and the market has matured enough that people can mod how they want the car to be.
I still say 2009 is when people will consider the tc as a trade in for the sc since there is nothing out for the car right now and its still months away from even being released.
So before you start saying I don't know **** about people that own the cobalt how about looking at the join date of the person your talking to.
