It is parked next to the 1968 Bizzarini Manta by Giugiaro.
The Liza GTR definitely looks like a purpose-built racing car, having no headlights, and questionable build quality. It does seem to have gullwing doors.
"Liza GTR" is not an easy phrase to Google. I suspect the car could be called "The Liza GTR by M. Kaneko". The main sponsor of the car may be KMCE. More information might be available, by searching for a race driver named M. Sato, who was active in 1969.
(Sorry if I point out the obvious. Sometimes it can help to find more info)
