Marc,

My friend with the Mustang and Corsair charges $1000.00/hour for a ride in the P-51, which is relatively cheap. Lots of gas and wear and tear. I have been blessed by many rides in the P-51. I am glad I am not paying the bills! When I can figure it out I will post a picture of a formation ride I recently went on.

At those prices I'll bet he isn't including rebuild-cost-per-hour on either of those two magnificent engines. You have a really good friend to take you riding! :-) God Bless, Marc

No doubt. However, when he decided to do an overhaul on the Merlin he chose to keep it as a showpiece at his museum and put a completely new overhaul back in the Mustang. A core engine is worth about $70,000.00, so it is like having a $70,000.00 door stop.

The first website is for the museum and the second is more of an unofficial website of his museum, you can see his plane, as well as my L-2 'Looking For Trouble" in the pictures.

This link will show my L-2 toward the bottom of the page:

Sadly I wouldn't have bought mine with an automatic, and as happy as I am with it, I still won't. For me automatics go to te big guns like our drag truck or a heavy 4x4, even my 4x4 ranger was a 5-speed, I'm not knockin auto's or those who prefer, it's purely my preference so an extra gear would be nice.

Imagine what an old box van would get ??
My last car was a 1986 Vanagon...
At 70 MPH, all buttoned up, non-functional AC off, I could sometimes do 20MPG on a cruise. That's on the stock, 2.1L 4cyl, 95 HP engine. And that is 3 over EPA.
I love my HHR, I can finally accelerate up hill.

Marty-an uncle of mine used to own B-25s.Over the course of his life,he had 3 of them.Before he died,he sold his last one(a B-25J) to General William Lyons out in California,whose pilot said that it was the nicest flying B-25 he'd ever encountered.

I don't know if the formula is the same for cars as it is buses and RVs, but I heard that for every mile an hour above 65, the wind resistance is not quite 3 times as much. So going from 65 to 75 would increase the resistance over 30 times. Not to mention aerodynamics are tricky. If you look at old RVs, they have slanted windshields, but new ones are almost straight up and down and yet are more aerodynamic. I definately think the HHR looks a bit boxy to the eye, but when it comes to airflow it is anything but.
