Are you sure it is 1SZ? What year is the car?

In 2005 there was a 1SX preferred option group which is the equivelant of todays 1LT. Basic, stripped down base model car. It could also be a typo if it is a 2005, '06, or '07 as a juxtapostion of Z51 which is the RPO for the performance handling package which adds additional transmission and oil cooling, different sway bars, bigger crossed drilled brakes and in the manual a different gearing for the transmission for more low end performance.

For what year?
In 2005 they had different interior codes then they have now.

1SX=1LT
1SA=2LT
1SB=3LT
Is this what your refering to?

1SZ is the Preferred Equipment Savings RPO, there is no "content" per se.

Right. 1SX was the base C6 in 2005 for the coupe with no options.

Actually it doesn't. 1SZ doesn't mean anything, there isn't a 1SZ. The 1SX was the base 2005, it was the equivelant of the 1LT today.

I think you got it right as that is what it says on the invoice.

I had the same question. My order form for my C8 says 1SZ for my highly optioned 2LT.
Have no clue what it means. It does not seem to be connected to anything at all.
Just says discount option package. So I assume that some of the options I got are less money as a group than individually.

Some reason why you posted that here instead of posting it in the C8 forum?

Especially since you had to revive a 12 year old thread.
