Since acquiring my 1970 Series I 240Z two years ago, I have driven over 20,000 miles. So I guess it qualifies as a daily driver. Trailer queens are not for me. Part of the gestalt off a car involves going from point A to point B on demand. During this time I have had two extended periods of non-availability, one, to install AC and two, repairs after I was rear-ended. Since I now do most of my maintenance, I have systematically gone through each area of the car renewing their functions. I have had jobs that take the car down overnight, mostly due to needing to replace additional components once I've started a task. Fortunately, I have my wife's car as a back-up in these situations. One such example was needing new O-rings for the end caps when replacing bearings in the differential. And after 44 years of questionable maintenance, I have to say I've had to fix at least one shoddy repair for each case of truly worn out component. The major difference between repairing a Datsun versus an old Ford, Chevy, etc is that almost any part takes a day or longer to get. So if you don't have a back up vehicle, you are apt to find yourself walking from time to time. However, on the good side, my Z has never left me stranded.
