Hey Scotty! I am looking for a used SUV similar to the Toyota 4Runner in terms of reliability,size,4wd, and towing capacity but with better gas mileage, year 2010 or newer and under 15k. Any ideas?
I don't think there's any body on frame 4x4 Suv's comparable to the 4-runner will have remarkably better mileage and be as reliable. In today's pandemic fueled high used car prices, good luck finding a 2010 anything 4x4 under 15k with reasonable mileage.
There is no way you will find a vehicle that meets all those constraints. One or more of those parameters will need to be relaxed and/or you have to determine which one (or ones) you prioritize the most.
TBH, I don't think there is anything like the 4Runner on the market, as most SUV's now a days are built unibody, whereas the 4Runner is body on frame.
The only two that would come close to fitting what you are looking for is a Toyota Highlander and a Honda Pilot. These are Unibody construction.
