Orange, you're right, YMMV.
I rented from Advantage once. The price quote was much lower than Thrifty, Hertz, Avis, etc. But it ended up being the same or higher when they got through with the hidden charges. The car was complete sh*t. It had around 70,000 kilometers, was trashed inside and steering was difficult. If it hadn't been late at night, and Thrifty next door hadn't already closed, I wouldn't have accepted the car.
A colleague of mine rented from Economy downtown in San Jose. I told him beforehand to make damn sure he didn't rent from Advantage. I found out later that Advantage and Economy in Costa Rica are the same company. The van we ended up with was in poor condition, compared to your average rental vehicle. He had an accident, and for reasons I don't exactly remember had real problems. I do remember the insurance didn't cover it, and his cost to get the vehicle fixed was more than it should have been.
Apparently I'm not the only one -- I didn't write these, just ran across them as I was trying to refresh my memory as to whether "Economy" was the other name they go by:
