Hey, there's nothing wrong with having rules to moderate (or enable) impulse buying. True story: I had been looking at Mazda's twin-turbocharged RX-7. I already had a fire-breathing sports-car. I didn't really need this thing. But I really liked it. I've been into R/C model airplanes my entire life and have always had a particular attraction to high-end, high-performance gliders. One fine Sunday afternoon I was coming back from a flying session and decided to stop by the dealership to check out the RX-7 one more time. The sales guy pressured as they usually do. For some reason I put a stupid challenge on the table. I said: "I have a 2.5 meter glider wing in my car right now. If it fits into the twin-turbo RX-7, I'll buy it." I drove the RX-7 home that day.
