I think it sounds like you bought it and it is only your own fault. The only thing that is shady is the blacked out logo on the truss rod cover. Despite the post about the bleached blonde thumb, the maple neck on a Corvette should at least make you look a little closer next time. Not that there are none-for example there is a Masterbuilt NT Corvette in bubinga or ash with a maple neck. But if you see one, you should look more closely.
The Korean models from past were more in line with the price point of the German Pro Series (GPS) as a middle ground between the custom Masterbuilt shop and the Rockbass line. I think the Alien deluxe may still be manufactured in Korea. The Corvette Prolines were budget friendly German made basses in the 90s. They were the first bolt on necks at Warwick.
