i like the k-pipe better than the grom, better specs, simpler. but the grom's definitely without question gonna last longer and hold value better.
the romet is sweet, how'd you register it? I was in germany for 2 months in '16, I wanted to buy a moped but I was technically on a business trip, so not a resident, and thus couldnt have registered it.
We also toyed with the idea of buying bikes in india and riding them with our friend aditya for some long trip, but same issue - how to register (although in india i'm sure you could get away with it, but germany? no way)
I just wound up renting a kymco scooter for like 15 bucks a day and touring around on that (i put just under 1000km on it in one weekend, the rental dudes charge mileage on every other bike but never expected me to go halfway across the rhineland and Baden in a weekend on a 35kph scooter...)
