That's Seiji Ara's old car; it's been for on and off for sale for about 4 years. It's chassis #17 with engine #16. The interior is different than the "standard issue" Z-Tune since it was custom-built for him. It has black Alcantara inserts instead of the regular red ones.
It might actually be engine #18, I can't remember exactly as it's been awhile.Why does it have the engine from #16 in it?
