I've been to the autocollections a couple of times and have really liked it. Why the three stars then?
Granted I went there a couple of months ago and they are constantly changing the cars the have there, but I do not recall seeing that many american cars. They usually have a couple of mustangs, pontiac gto's, chevy biscanes, eleanor from gone in 60 seconds with nick cage, etc...
Now that I think of it; I do not remember if they even had johnny's carson donated car, or howard hughes' vechile. Ok; maybe the johnny carson car will always be there, but when I went I was suprised at the total lack of american cars and that why I have to rate only 3 stars.
P.S. You can to to the autcollections webstie, or browse those funbooks for free show tickets so you will not pay admission fees. I've been there and never had to pay.
