i made it to zaz yesterday. it was a small place but it had amazing supercars. photography was forbidden and there were security cameras everywhere. i had to do some serious sweet talking through my translator...eventually they relented and even opened up the barriers and allowed me to sit in the lm and take pictures. the gt was the maroon car, repainted. it was locked and they couldnt find the key so i wasnt able to get into it. i hope the serial number is known because i couldnt really see it in the dim light. perhaps it will be visible after touching up one of the several pics i took through the windscreen. i will post the pics after i get home, in a couple of days.
other notable cars were f40, f40 lm, jaguar xjr 15, and a pearl white fxx to match the owners pearl white enzo. the owners own a bunch of casinos/slot machine halls called pachinko in japan, their company is called called zent and the main division is called zaz amusement.
the cars are not driven too often, perhaps twice a year. once for a festival in the summer, once around xmas.
the owner had a white f1 as well, it was sold back to the factory and from there...i hope peloton/hurst or one of the other experts knows.
there was a lot of information about the gtrs and the racing scene but my translator had a sore throat by then, so i guess that will have to wait till my next visit. apparently a green f1 is on display a half hour away. and there is some connection to someone named Mark in Australia who owns a Ford dealership. He has two McLaren F1s, including the Lark GTR, if I understood it all correctly.
this place is far, far away from tokyo. two hours by train to nagoya. then another half hour by local subway train to fugikawa. then a half hour by bus to the second to last stop. i was planning on going there on my own, but thank god i didnt--i would never have been able to find the right trains and buses and it would have killed the day. i dont recommend visiting zent museum unless you speak japanese or have the street address and plan on driving there in a car with sat nav.
