Are you visiting for business or vacation?
I live very close to Leiden (about 10Km away)
I presently own both a US Supercharged Acura NSX and a EU Honda NSX (is for sale by the way), but there really isn't anything much different between the two (speedo Mls vs Km, AC F vs C, foglights and headlight washers on the EU car, sidemarkers on the US vs none on the EU car and that really is it)
I am not sure if I will be available, but you could try to hook up with me and possibly I could treat you to a little NSX drive through the Dutch countryside.
Best email me direct at: [email protected] and I can give you a phone # where you can reach me when you are in Holland.
