If the engine management computer dies then the engine stops working, yes. But we're not at the point yet where just because one part of your car dies you throw away the whole car. That's because there's this technology that's still not quite dead yet called "repair". Perhaps you're young and haven't heard of it. You take your car to someone called a "mechanic"; they figure out which parts of the car are broken, and they replace them. Car manufacturers have very cleverly made their cars so that many of the parts are interchangeable, which means that instead of tossing out the whole car, your mechanic just tosses out the broken parts, and puts in new ones at much less than the cost of the whole car. -- Tim Wescott Control system and signal processing consulting www.wescottdesign.com

That presumes that: a) the "mechanic" can actually identify the broken part, and: b) a replacement part is actually available. a) usually happens, but I often have problems with b). Older cars. The last time I had a problen with b), after a lot of digging around I found the part on Amazon.com ???
