Can't speak to the P5 but we have had a Par Car for the last 4 years and love it. Speed is 20MPH max and the dealer won't change it unless you go street legal. I have it serviced by Todd Casey since I find no upside to having it serviced by the dealer.....and electrics require less service than gas. Range has never been an issue and if the P5 has an AC motor you may get better performance and range but we go from Hillsborough to Spanish Springs area to play golf (champ course) and return without issues. It's good to live in the middle
