NEW YORK ( TheStreet) -- Have you been to an auto dealer lately? Their lots are full of customers. My salesman could not even find an open desk to sit with me. We finally had to settle on one without the hot lights. I just hate the whole car-buying experience.Nevertheless, now is a great time to buy a car. The economy is on the mend, interest rates are still relatively dirt cheap, and the automakers continue to innovate. Lithia Motors ( LAD), which is headquartered in Medford, Ore., is a good proxy as to just how strong auto sales have been recently. Lithia operates 87 car dealerships in 11 western states offering 27 brands of used cars and light trucks.
