Warren,
Nice picture but with a house of that value I would be a little concerned about that one tree. Sounds as if it is in your mad money range. Why don't you buy it and use it as your vacation place. Replace the tennis courts with a huge garage just for all the cars you will collect.
I watched the show on Jay Leno's new garage that is all solar powered last night and what a garage. I think they said around 18,000 square feet but I was looking at the cars and not paying much attention to the ramblings. This is what they are going to use as a model to encourage all people to build this way. If I had the millions that he spent on that place, I would build a lot smaller garage and then get a few super cars for it. But it is nice and a marvel of technology.
