I politely disagree. The symptoms sound like classic glowplug failure. Runs rough at first. Runs fine when hot. Starts and runs smooth after hot.
It would certainly be the first place to recommend a new owner to check, before we start guiding him to pulling injectors and pop-testing.
Do the easy and more common stuff first.

Nope, the glow plug light didn't turn on at all. I was kinda worried bc I don't know when the glow plugs kick in??How can I tell when they do? My uncle changed the instrunment cluster and said that not all the lights work. I got the old one also so I was thinking of swapping bulbs. Now if the light doesn't kick on does that mean that a glow plug is bad??
My uncle aslo said he swapped 2 glow plugs some time ago, and he still had 3 more to install. I'm skeptical about the Autolite glow plugs...anybody using them????
I paid $900 on this car and I'm planing to keep it until I get out of college.

Autolite glow plugs do not have a good reputation on Mercedes cars. They just don't last very long at all. Use Bosch or Beru.
