Yes, 14 coupes in that colour. It is a 1985 model, and is No. 14/14. Its the dark blue colour, in case you're wondering.
He said he can ask a fellow he knows over there to find out exactly how many 13B manual coupes were made.
The person he can ask is a car collector and historian, so should be able to find out.
If you really wanted to own it, the owner will sell, but from what I can gather, it won't be for less than 600 000 JPY. I'm told its immaculate condition with very low kilometres.
I passed on it myself, as I'm holding out for a 12AT one, apparently there's not much power to be made from a 13B RESI.
