Good job! You did exactly the same thing I did, except I bought a "Titanium" silver one with 74,000 miles on it. You will actually learn to love your 4Runner more, the longer you own it! I just drove mine clear across the country, from Maryland to Los Angeles CA, and I'm constantly amazed at how competent (and downright FAST) this truck is.
One word of warning: Toyota's marketing plan is apparently the same as Harley-Davidson's, to wit: your truck will never ever ever be exactly the way you want it. There will ALWAYS be
"just one more thing" to buy for it, to make it run better, or look better, or work better off-road, or sound better (stereo/CD, Sirius, etc). You have been warned!! And you're right, there are a great bunch of people here, gearheads all, and the knowledge available is staggering. Enjoy, and welcome to the forum!!
