@ germ-x. Haven't been burned but I've seen enough accounts of people who have been burned to know enough to take steps to avoid it. I did have an image save my bacon (and data) a few years ago when a program (Threatfire) scrambled my OS. Thank God I not only kept backups but I also kept versioned backups.
@ whs. Yeah, Saoirse (my F150) is a thirsty girl compared to your cars but she has her advantages. She seats five comfortably and a sixth person if that person isn't too long legged. She has loads of cargo capacity (I love the tool boxes on the side of the shell!). Even though it's a large step up (thank God for step bars), she is much easier for me to get in and out of. Because of bad joints, etc. I have a hard time getting in and out of most vehicles; I often have to have help getting out of compacts. And the ride in most vehicles is very uncomfortable for me; Saoirse is very comfortable, even on long trips.
I have no idea how fast she will go since I've never opened her up (no need or desire to) but I'm guessing she could easily top 120 mph. She can easily hold her speed on any grade I've had her on (6% or so). I drive her as though she had eggs taped to the gas and brake pedals so she gets pretty decent gas mileage for a vehicle her size. The last time I checked, she was doing 17 mpg city and 19 mpg highway (I drive the speed limits; less if conditions require it).
Diesels aren't available for the F150s. Ford truck diesel engines burn less fuel than an equivalent gasser but diesel fuel prices are higher. They can go farther with less maintenance but, when maintenance is needed, it costs more than a gasser because they usually have larger sumps that hold more. Repairs are less frequent but are also more expensive. The initial cost of a diesel engine is higher than a gasser. Overall, gas engines are far more economical than diesels. Diesels shine in Ford pickups when one is doing frequent heavy towing.
