I purchased this vehicle new and it has been the most reliable vehicle I have owned. I've had other brands Honda's, Chevy's, Ford, GMC.... and nothing compares to Toyota quality and reliability (not even my Honda Accord). The only maintenance has been oil changes, tires, timing belt per owners manual and brakes (probably weakest feature - upgraded to Tundra front discs last year). I would buy another 4Runner, but this one still has years of reliable service left.
Bigger front discs, maybe a V8 (power) for Colorado passes towing a trailer. The ride is a little firm, similar to my old 911.
