If I had to pick a car for a daily driver, I would choose the XK8 without a second thought. Much more reliable, much easier for me to drive and whatnot. My friend owns a '71 XKE convertible and just to drive it I would have to shrink the steering wheel about 2". As it is, I sit about level with the windshield trim. It would make a hideous daily driver for me. With a little work, such as lower bucketed seats and whatnot, I could probably turn it into a decent driving car, but I could not picture myself driving the XKE every day.
