I owned an actual Monza Mirage. It was my very first car. The wide body panels had been torn off by someone prior to my owning it. I never could find a replacement set.
Sadly, I got t-boned by a speeding driver broke my hand in the accident, but the car was toasted as the body had been completely sprung.
Oh, how I miss that car.
I built the MPC Monza Pro Street kit as a Mirage - scratch building my own body kit. I sure wish they would reissue these kits.
