Thanks.

I actually did the drive up to the summit about 6 years ago, and I couldn't remember how much we paid for a 4x4 Jeep but it was much less than $200/day (the current quote on Alamo).

I also remember seeing all kinds of cars at the top - sedans, compacts, etc. I think I even saw a Buick LeSabre which was quite funny at the time. But... I'm really not a rule breaker when it comes to these kinds of things. Are they still strict about having a 4x4 past a certain altitude?
