No way I'd pay even close to that for such an out-dated 4Runner. Then again, I guess most people are not me. I'm waiting for the next redesign of the 4R and the Sequoia. Till then, I'll add a GL450 to the stable (mainly for gear room + 3rd row) and let it get us through a couple of years.
Used vehicles are off the charts too. Well, some of them like Toyotas and Wranglers. My 2015 Rubicon is now worth mid 40s. Low miles for sure but still quite surprising. I may sell it though knowing me, I'll prob end up with another one in due course.
The 2005 4R stays. It is just a workhorse.
