Lol agreed and there are very few vehicles on the planet that have an positive ROI, they all depreciate and quickly. Some more than others.Thanks. yes, that is true. Also factor in the additional cost for the engine upgrade and higher maintenance costs. There is likely no ROI. But who are we kidding - We would buy a Prius if we really cared about things like ROI - That big smile you get when driving is all the ROI you need. Spooling up the turbo and rolling coal in the Super Duty also gives me that big smile so I totally get it.
