whelp, got mine done today. SmartCenter of Smithtown changed the secondary air valve, installed my trunk divider w/net, and checked a false warning on the "tire getting low" thingy.
all in about an hour. had a little coffee they had there (Starbucks, no less

), did some paperwork, and was on my way with a freshly washed car and only $48 out of my pocket.
doesn't get much better than that fellas.
