My car–an automatic Saab 9-3 Sportcombi wagon–has been in the shop since a week ago Wednesday to repair various problems in the radio and navigation system. I bought it used two years ago with the factory warranty in place. I’ve been contentedly driving a loaner, a standard 9-3 sedan. In fact, I like the loaner more than my own. It’s peppier, more fun to drive, gets better mileage, and is easier to park. I have never been as relaxed about a car being in the shop. I do not call to bug them. When they call to say “we’re still trying to figure out what’s wrong” (how did the amplifier get corrosion? It’s mounted underneath the cargo compartment. Did the dogs drool seep through the floor?) or “we’re waiting for a part” I say “no problem” and keep the loaner for another day. I wonder what I could get on a trade-in for a used 9-3 sedan.
