RYT,
Sounds like you have a great car. I'm sure whatever you paid, it was well worth it. And 160kmi is low for these cars (although maybe not low for Hawaii.)
Both of mine have nearly a quarter-million miles! Maybe post some photos of your new baby if you have a chance. Photos of mine, including the modifications done, are here:
