TIS, I've been to Graceland about 15 years ago, give or take, and I saw the car collection and the plane. Maybe I'll dig up some old photos to scan and upload one day when I'm not too lazy.
I have to say the tour is not that long; you can wrap it all in under one hour. I don't remember prices and whether it was extended tour, but the car collection was probably the nicest thing to watch there.
If it's not that big a sum, and you're not gonna go there again, then sure go for extended. And like I said, it's not that long a tour. Don't think you'll spend the whole day there.
Graceland aside, there's a place in Memphis called "Mud Island River Park". Not sure if it's still there, but look it up if you need some place to relax and spend the day.
"Come out and take it, you dirty, yellow-bellied rat, or I'll give it to you through the door!"
