I actually took a tape measure to work one day and measured how high off the ground the bottom step is on different type Package Cars. The new P7s are 14 inches, a P5 is 17 inches, and the P8 and P10s are 20 inches off the ground. While a couple of inches might not seem to be much, when you step off and on over a hundred times a day, it does wear out knees and feet over a period of time. I think all the P8s should have been scrapped years ago. I have seen a lot of injuries from these things over the years. The newer cars do seem to designed better, with lower ground clearence, power steering and brakes, and automatic transmissions.
