Even our own knowledgeable moderator RJ can make those common mistakes.

(Listed it LT1, LT2 when he knows the correct way is 1LT, 2LT )

Sorry RJ. Just a little to start the morning

 

Dangit, I did, didn't I? I didn't even realize...

 

So, anyway there is really no difference between 1LT and 2LT, except the fancy wheels. I can't tell the difference between FE1 and FE3, I think the chrome package was available on 1LT, the sunroof was available, the 2.4L was available.

When I was first considering an HHR I looked at the options available and couldn't seem find anything but the sunroof that wasn't standard equipment.

 

I believe the sunroof and leather interior was only optional in the 2LT
The FE1 is the standard buckboard Suspension
The FE3 was an upgraded spring rate and shocks with a smoother ride.
