So at least on the surface of it, the gen2's front seat height could be roughly 6" higher than that of gen1 (if we can assume about the same roof thicknesses), given that they seem to have about the same roof heights...
OK... first of all, seat height , headroom, and vehicle height are all separate dimensions. And less headroom in the 2nd gen could
actually translate to equal
seat height for the 1st and 2nd gen, but with less headroom in the 2nd gen due to a lower roof. Or, if the headroom is less in the 2nd gen they might have reduced the height of the seat (relative to the floor of the car) accordingly to maintain relative headroom. But this is just speculation since I've not actually measured anything myself.
Now... about the vehicle height... I've seen different specs floating around but have generally seen 1st gen 65" and 2nd gen 63". But the whole problem with these specs is you don't know where they are measuring that on the 2nd gen. If the 65" is accurate for the 1st gen, (and I believe it is) it is a good measure of how high the roof is (at least on the outside) over the driver's head since the 1st gen has a perfectly even roof from front to back. But the 2nd gen's roof is lower in the front and higher in the back. So if the 63" spec is a measurement of the roof at its highest
point, then that could mean that the roof is lower than 63" at the point that is directly over the driver's head. So my guess would be that the difference in specs that you see is due to different measuring methods and a lack of standardization thereof.
But what really counts as far as seat height goes (as far as I'm concerned) is how far the seat cushion is from the floor of the car. In other words, it's not so much how high you sit relative to the street and other cars, but how high off the floor of the car you are in that matters most.
