Normally be running P1 on 2-3 of the vehicles I maintain. But currently running a P1 on a Tacoma, a BD+ on an Accord for two oci's, and a non ecore STP, part of an oil change promo, on a Civic.
I've currently got a few P1's, a couple BD+'s and a couple Napa Golds in my stash, all purchased at nice discount.
