So what options are worth the extra cost in the long run?
-Leather vs cloth: Ive had leather, and ive seen the leather seats of 4runners and Sequoias...cracks and ugly. Plenty ugly IMO. I like that i can shampoo and clean my cloth seats and these things dont rip. My 03's cloth seats still look fantastic.
-X-REAS vs non: Both mine have XREAS, and regardless if you have it or not, you can change it out to FJ springs and Bilsteins if you want to. You just have to remove the XREAS completely should you choose to do so.
-V6 vs V8: I have two (2) V8's. I drove the V6 first, loved the fulltime 4wd and power of the V8. I still get 18-20 mpg from my V8's and yes, the timing belt, water pump and 90k service isnt cheap, but when you get the rig back from the shop afterwards, the thing is practically new and good for another 90k!
-Sunroof vs non: Are you tall? If so, you might find the roof lower with the sunroof. Yes, there have been documented decay issues, but its something to keep an eye out for. My 03 has a little underneath the weather seal stipping for the rear door. I took a wire brush, clean it, wiped it down to a shine with alcohol, 3x primer, 3x paint, 3x clear coat. Its been cool since.
-Nav vs non: My Iphone 4S has better nav that the OEM deck. Besides, i switched them out for Scion decks anyways.
-JBL vs non: I like a good sound system. I used to have 20" subs and crossovers and amps, etc etc...but im over 30, and the days of "bumpin' down the blvd" are over.
-Various years? I have the 03 Sport Edition V8 and an 08 Sport Edition V8. The 08 has the slight body changes, the 03 has the grey textured sport cladding trim. I love them both...but there's a special place in my heart for the textured grey 03. It was so short-lived that i see it as a limited edition.
Good luck with your 4runner hunt!
