5.4 good strong engine. That model in demand...so price is probably up. Nice unit. Ask yourself how many miles you planning on per year? I have model that ca pushed out to make room for 19 model. We put on about 6k a year. And have money if it needs repowered. 250k miles or so is what i planned on for life span of engine. Many get lots more. CA changes engine oil per book. Unit hasnt sat around rotting in place. Had outs 8 years...front end work. Brakes couple coil over plugs and had to pull injectors and clean them thanks to sea foam. Doing work myself probably 3k in parts since 2008 includes tires. Leaves driveway l ittle over 12000 pounds. 5.4 hums along but would like more power.
