Is your car diecast or plastic and what scale is it?
The reason that I ask, is because I own one of the 1:18th scale diecast versions of the 1968 Dick Landy Super Stock Dart that were produced in a limited production run of 1500 by Die-Cast Promotions / Highway 61 for Performance Years Enterprises under stock #50242 back in 2004.
Your car looks similar, but I do notice some differences at a quick glance between the two cars. The decals all over the car are somewhat different, there is no outside rear view mirror on the passenger side door, or GTS emblem on the hood of my diecast car and my car also doesn't have any windshield wiper arms on it. My car does has the dash mounted tach though, which I don't see on your car. I'm sure that there are other differences if I looked harder, but I'm only asking because I'm curious. I've posted a web site link to the Performance Years Enterprises web site below so that you, or anybody else who is interested can see pictures and read the information about this 1:18th scale diecast version of this awesome car.
All I can say is, if your car is a plastic kit, or a custom built car that you've done, my hats off to you, because that is one EXTREMELY well done car!!!
