it really depends… there were 2 different grills, and they dont help identify a year… there were the flush stock grills, and sport grills avail as an option that were set in more…
the big way to identify year is hood/rear bumper… if he had split dual exhaust and hood scoops… it was an 05/06 LS2… if he had dual exhaust but only on the drivers side and a smooth hood, it was an 04 LS1…
the only black 04 i saw at starlite was spraying and it was an older gentleman
theres a kid named john that comes around with one too, he has powercoated stock rims and a SLP loudmouth exhaust… but hes an auto
if it was a black 05/06… the 2 that were in our row, we drove to primanti bros together so it was not us, we did come upon another black 06 on 19 at the light by 910, and we talked to him a bit at the light and then he split off of 19… so it may have been him, but he had some white pontiac stickers on it…
