The post from financial blog fivecentnickel.com that's linked below offers ten car-buying mistakes to avoid in today's market, and some tips on how to avoid them. There's something for both new- and used-car buyers, so I'd recommend that checking it out if you're shopping for a car. Add up the financial impact of the items on this list, and you're easily talking about several thousand dollars. Probably my favorite suggestion is to remember that you're shopping for a vehicle, not a good deal. The number of cars sold during zero-percent financing and employee-discount promos suggests that either millions of people had a sudden need for a new vehicle that just happened to coincide with those incentive offerings, or that there's a lot of people that simply got hooked by a good marketing scheme.
