What is this ?

I believe all 2nd gen cudas had "H" as trim level. Has no bearing on it being an S or not.
OP hasnt been back, must have not liked the answers lol.
Get the back seat cushion out, & see if You've got a VIN matching broadcast sheet, if so all of Your answers are right there.
As SSD called it out, H is High Line trim, so a real chance it is an "S" model...how 'bout some pics...We luuuuv pics!!!
