OK, I'll give this a stab...
1. Of the 47 remaining cars - how many are in private hands, and therefore might potentially come up for sale someday? I assume the museum cars will never be sold, and I hear also that some private cars are intended to be donated to museums in the future, therefore the number of cars which might actually be offered for sale at some point must be quite low?
I'll let you do the math - http://www.tuckerclub.org/html/see_a_tucker.php
2. What is the highest recorded mileage which a Tucker has driven?
Really don't have any records on this one, except that Tucker 1014 was reported to have 110,000 miles on the odometer back in 1954. No information on what was rebuilt or repaced at that point.
3. In general, were the cars driven as if they were just any other car for the first decade? Or, were some/most cars bought as investments after the company folded, and stored instead of driven?
Perhaps with the exception of the Tuckers that Mr. Jones used to take on the road to County Fairs, I don't think any of the cars were purchased back then with the intention of making money.
4. Compared to another car from the same period, how reliable was the Tucker car as an everyday driver? I guess nowadays they are harder to maintain than a Ford of the same era, as some Tucker parts are rare...?
Since the cars were basically prototypes, there were lots of kinks to work out, as well as lots of differences from car to car. Nick Jenin converted 1046 to and Oldsmobile chassis in the early 1950s so his daughter could get the car serviced easier. I guess that speaks more to finding a good mechanic than the reliability of the car itself.
5. Are there any Tuckers in private hands which are driven regularly? How many miles per year are covered in this case?
I'd say the best example of a Tucker that is driven regularly is 1041 owned by TACA members Bev and Dorothy Ferriera. They are very adamant that the car be driven and not trailered, and while Bev is getting older and does not drive it as much as he used to, they were very active in taking the car to local car shows. At our last convention in Las Vegas, Bev drove the car all the way from San Francisco with an air conditioner hanging out of the window. He did a few laps around Las Vegas Motor Speedway and as I recall, when he got out with a huge grin on his face, he said he had it up around 95 mph. I wish I had videotaped that.
6. What is the consensus on replica Tuckers - are they good for the image of the car? As owning an original Tucker is unlikely to happen for 99.9% of Tucker enthusiasts (due to their value and rarity), would most people here still like to own a fiberglass replica?
There isn't much to come to a consensus over. The only successful replica was Ida's, and at $200,000 if you could afford that, you could probably afford a real one. But it was a beautifully done car.
7. What was the average value for a Tucker before the movie came out, and how long after the movie's release was it before they started to sell for hundreds of thousands of $$$?
Tuckers sold for about $60,000-$80,000 before the movie. I remember seeing one for sale right after the movie for $1,000,000. It never sold for this, but I think back then they settled in around $200,000-$300,000. Of course now they're more like $500,000-$700,000 for a nice car.
