for the bonnevilles
SE=sexy edition
SSE=super stealthy edition
SLE=super lazy edition
SSEI=super secret engine inside
i stole the last one from dan but id like to know what other peoples anlaysys on the trim levels are

SE-Sissy Edition
SSE- Subaru Smoker Edition

i like your se better than mine.mine sucked it was the first thing that came to mind

I might be biased etc...but you asked and brutally honest how I roll.

SE = Slow Edition
SLE = SLow Editiion (JimmyFloyd credited for walking over to one at a meet and saying "Hey they spelled SLowE wrong")
SSE = Still Slow Edition
SSEi = I forget..
GXP = Gimpy X Poop

Don't worry, I gotcha Bill.

SSEi = Supercharged Sedan Everything inside.

That'* around the right thing.

Of course I may have been a bit biased in those names, does it show? lol

SLE = Sport Luxury Edition
According to a site I stumbled upon one day, a bunch of people called up Pontiac and apparently that'* the only trim level designation that actually means anything, the rest are just letters. May or may not be true

And now for my takes:
SE = standard edition
SSE = super standard edition
SSEi = super sexy engine inside

SE - Stripped Edition
SLE - Something Less Expensive
SSE - Seriously Something Extra
SSEi - Seriously Smoking Everyone'* Import
GXP - Given Extra Parts

See, in my mind, it goes something like this...

SE=Sport Edition
SLE=Sport Luxury Edition
SSE=Super Sport Edition
SSEi=Super Sport Edition intensified (lame, I know)
GXP=Given Extra Power
The only reason I say that they are Sport and Super Sport is because I remembered that they were the better trims pre-1992. And my GXP is strangely similar to Steve'*, strange.
