SRS... salesmanship...

"Nah, tha brakes work fine but the sensor is messed up. Of course, it could be the computer chip but I can't see how that could happen. If it's a deal breaker, I'll take $500, which would easily cover the cost of the sensor, off the price IF you take it today. Can't promise the same deal tomorrow. Take it for a spin, try the brakes, think it over and let me know."

I once (at Kmart when I was a teenager working in sporting goods) sold a complete fly fishing outfit... reel, rod, lines, flies, vest, waders, boat, motor, trailer and, most importantly, fly dope to a guy I met in the pharmacy department who was buying tampons. I said, "Buddy, yer weekend's shot so you may as well go fishing."
