I went with state for no other reason than I've got other stuff with them the odd time I've needed to claim they didn't give me any probs. (non bike though)
The 400 km trips were just for fun, there are at least two other Jogs that have gone way further "Carver" is one.
The first two should be at the dealer you purchase it from just to cover the warranty.
Take the first 500ks reasonably gently but don't baby it, you have a fresh engine to run in, new tyres to scrub and believe it or not the drive belt needs to be run in a bit as well.
Most of the time your riding it like you stole it so maintain the simple stuff like the air filter (washable), plug, gear oil. Tyre pressure makes a difference. If your right into DIY get a cable lube tool.
There are plenty of good second hand ones around that will save a few bucks some with a givi box on the back.
