I don't even drive at 70 mph up the Alps _without_ a trailer, because
the streets there are not only high and steep, but also quite narrow and
curvy.

You'd be surprized what you can do with astonishingly few horsepower.
Agreed, towing a double seater may be a bit harder, but still works with
70 hp. Maybe not at 70 mph uphill, but who cares? How often do you tow a
trailer? Once or twice a year for holidays and twice or thrice for a
retrieve, ant that's it in most cases. For me, spending two or three
hours more in a year for towing (assuming the worst case scenario) is
much better than having to drive an insane SUV the whole year. But then,
we don't occupy distant countries to ensure our oil supply, either.
