Used cars in particular. Cash for clunkers did that, but new cars actually can be surprising...Nissan is advertising a sedan for a base price of 10k. For the first time in my life I would give actually serious consideration to buying a new car.
When I graduated from high-school in 1985 a new Dodge Ram went for less than 5k. Did not buy a brand new car until 2006. I bought a used 9 year old Ram with 40k miles for 5k last year.I too think it is ridiculous that the average new vehicle can cost half as much as what my house is worth. The house at least has the potential of being an investment. An automobile in 99.9% of most cases is a losing proposition. Worse come to worse there's always a bicycle.
The great irony... "Foreign" cars, Toyota, Honda, etc. are made in the USA by American workers, designed by American enginners, and "domestic" cars, Chevrolet, Ford, Chysler, are made in foreign countries.
