1989 Pegasus 2000 by Pegasus Motorcars in Pasadena, Texas. Pegasus Motorcars is owned by Charlie Van Natter, who takes credit for building the car. (Model year of car may be 1988. The B.L. Stryker show that featured it, started broadcast in 1989)
I found pictures of a blue Pegasus 2000, in worn out condition. It certainly has Firebird doors, but it looks like the back seat may have been eliminated. It is a very short car.
Sadly, it looks like Pegasus Motorcars also makes (made?) a body kit for Chevy trucks. Picture the nose of the Pegasus 2000, on a pickup.
