Are orphan car brands like Pontiac and Saab good deals on the used car market? We answer that and discuss why the Volkswagen Passat doesn't feel all that "German" to drive. Then we look at the updated 2014 Volkswagen Jetta and redesigned 2014 Toyota Corolla. Other reader questions look at substitutes for the defunct Lincoln Town Car and Cadillac DTS, testing the diesel Audi A7 TDI, whether the Scion FRS and Subaru BR-Z are powerful enough for our tire test program, and how we purchase test cars.
