 Gas mileage for my 4Runner was equal to my previous Suburban. Passenger seat broke 3 months after purchase, rarely used. Driver's seat broke 2 yrs, & I had to pay half of $600.00 to fix it! Replaced brakes at approx 88,000 km, normal. Drives excellent, no major maintenance costs unlike the Suburban. But the side mirrors are in my face, and major blind spots. Friends who have driven my vehicle find the same problem. For this reason, I wouldn't buy another 4Runner. I have had too many near accidents due to this problem, and prior to this vehicle, I've never had so many potentials! Stereo could be better. 1 to 2 minutes for 4WD to engage & disengage! That's too long.
