I think the supra will help the value of the older ones. As the new generation of tuners see the powerhouse that the new Supra is they will be doing whatever they can to get there hands on any car with the supra name, thus making them more popular. When civics hit there prime we all started to see more and more of the older civics hitting the streets and "coming back to life". When the people that have forgotten about the Supra or werent lucky enough to know what a beast it was see what a beast the new one is, there research will point them in the direction of all the older Supras and they will see that 50,000+ dollars does not need to be spent to drive a car with the Supra name.
