There are actually many Super Autobacs stores located all over Japan. I went to the one in Tokyo Bay, because it's close to the famous Wangan highway where many high speed street races take place after midnight. The Tokyo Bay area is also famous because Tokyo Disneyland & Disney Sea are located there.

The train station to get off at is Shinonome, using the Rinkai line. You can see the store from the station, so you shouldn't get lost.

The Rinkai line isn't that complicated. From Tokyo Station, you need to take the Keiyo line and transfer at Shin Kiba to the Rinkai line. Shinonome is 2 or 3 stops from there.

If you start from Shinjuku station, get on the Rinkai line directly headed towards Shin Kiba. I don't recall how many stops, but you should get to Shinonome in about 30 minutes.

When I was there last month, they had this custom Monocraft MF1 RX-8 in their showroom.



I believe they sell the complete car or parts to turn your own RX-8 into a MF1 look a like.
