Corrados are pretty rare. The last ones on eBay went for big $$. One went for nearly $300 a few months back.
I talked w/Revell's marketing guy Ed Sexton recently at a show, and they are looking at possibly reissuing the Corrado. They are trying to find a solution to the tooling/molding of the kit. They realize that there's a decent market for the Corrado w/VW's and tuners being so popular now. There's a decent chance that if they ran the Corrado kit again that it would sell much better this time.
The Corrado was designed/tooled in a fashion that is simply very complex and expensive compared to other more traditional approaches. That's why the kit was so expensive in the first place, and rare today. It's because the company they used for the kit used a different type of molding technology and machinery that isn't common and is expensive.
To make a long story short, Revell is looking into reissuing the kit if they can afford to. They are looking at ways of trying to produce the kit, run the molds in a less-expensive manner.
I'm hoping...
