What shop did the car (TRG 111) come from? I'm in Tokyo for about another month.
I just picked up a new F104W MP4/5B from Super Rajikon in downtown Tokyo (Akihabara). 112000 JPY / about $138 usd Not much cheaper over here but compared to other items it's not a bad price.
Super Rajikon does have a mail order site http://www.super-rc.com
I spent about 3 hours in there and they have EVERYTHING in stock. I was shocked to see the amount of F1 stuff made these days.
I first had a Tamiya F102 and raced at the Tamiya USA track in the early 90's. It's good to see the car (F1's) are still going.
