I don't know. When I ordered the transponder for the 87, it was mailed to my address. It required make, model, and color and tag number. Model and color weren't among the click options in their menu, so that got the OTHER designation. My account shows Pontiac and my tag number. Just no charges. After Saturdays meeting, I checked when i got home and my truck charges for both ways was already on my account.
Hey! As long as they don't backcharge me for everything at once, I'm OK with it. Makes up for the $11+ I got hit for in the truck just a little before noon, one day. My normal charges run around $1.50 and sometimes less each way at the times I use the HOV lane.
