Thread: Cant tell what model Grand Prix i have, also a knocking sound

Hey guys
New to the forum. I recently purchased a 2004 Grand Prix for cheap ( 1900 under blue book) . The car has ran great and i was told about the struts needing to be replaced. Well i was online today looking for struts and realize there is several different options. I cant tell if i have the GT1, GT2, or GTP. The engine says 3800, but that doesnt help much. Also, the steering wheel says GP. Any way to tell what model i have?

Another thing, the engine, or something around the engine, makes a popping sound when driving, particularly when turning or shifting. I was told by 3 different mechanics it was the struts. On the car lift, i notice the struts twist and the engines moves a bit when the car goes from park to drive. So im assuming the mechs are right in saying its the struts. Also, there is grease leaking from the top of both struts, dead give away.
Well the past few days, theres a hard knock when going from second to third. I was thinking motor mounts, but all of them were replaced about a week before purchasing the car. Any ideas? Could the struts be causing this problem too?
Thanks in advance.

Gt1 is the base model with the 3 button dic usually with the cloth. Both gt1 and gt2 are non super charged if I remember correctly. Only gtp were supercharged 04-05

I had a gt2, was cloth, 3 button, no sunroof, no hud, but had widetrack. Showed up with autocheck as gt2 with the vin.

Says it on the dash by the rpms i believe. Think its a wider turning radius.

A little bit retro for you (but still applies to the 2004):
