My 15 yr old Jeep and DTS are about as old of a car as I'd want as a daily driver, and they are nearing the end..getting too unreliable. (I should be driving my '11 STS more, but it's in California currently). I couldn't imagine depending on something 25-50 yrs old, in the grind of daily traffic. I've got to have reliability, cold A/C, and all the modern creature comforts as well as modern safety features, brakes and tires. Old cars are neat as a weekend toy to go to car shows with, I wouldn't want one for the daily grind...
