The Nissan MID4-II looks like the love child of a 240SX and a 1st generation NSX. Interesting but not that much. However the Yamaha and the Isuzu would have been amazing to see and hear. 10,000 rpm V12? Lotus V8? Oh that sounds wonderful! Too bad they never happened in production guise. At least Yamaha helped give us the Lexus LFA V10 it's sound among other engines it helped Toyota with.
