I just bought a 2003 Dark Blue Limited V8 with 96K on it. Got it for $10,500 and think I got a steal. I towed a 2000 Crownline 180BR about 1,000 miles right after I bought it and you could hardly tell the boat was there, other than stopping frequently at gas stations.
Going down I drove 70-80 mph and got about 12.5 mpg going down the WV Turnpike which is windy and hilly. Coming back I kept it under 65 mph and got 13.6 mpg. Checked it the other day with no towing and combined city/highway and got about 17.5 mpg.
So far I really like the 4Runner and so does my wife. Been a Volvo guy since 1985 and recently bought a BMW 330xi and now a 4Runner. Luckily I read all about the Volvo XC90 which is what I thought I wanted, but reading about the 4Runner changed my mind. Pretty sure I'll be glad I did.
