VW Touran has a ground clearance of 156MM or 6.14 Inches and to total height of 1659mm or 65in , my Truck as a ground clearance of ~10in and a total height of 77in, that may seem like a small amount but is huge difference to me.
a VW Touran is exactly the type of vehicle I avoid
Further while available are not practical because there are very few mechanics that can work on them or have parts for them it has to go to the dealer which is $$$$$$
I tend to Stick to American Manufactured vehicles from Ford, Toyota, Honda, etc.
If you are 98 % of time driving on good roads, the generally lower center of mass makes things like a Touran or Toyota Verso safer and better to drive than a truck.
If you really need some more ground clearance, then there are things ranging from Honda CR-V (a very nice drive but a ground clearance closer to 8 inches) to Suzuki Jimny (a vehicle with actual off-road capability, but driveable on roads and small).
Of course there are people who actually do need a truck, but very often the cited reasons sound more like excuses.
Buying American, when you are yourself American, is of course a thing for many.
They are proportional, most Seats sit about the same height from the floor, so Ground Clearance it an accurate measurement to know how far the seat is from the ground.
(And they will tow the things that most people tow, like a trailer that weighs a ton).
