^^Appreciate your comments, suprarx7nut, but my car, while very nice, is not in the class of vehicles you describe in your first paragraph above. Your point is very well taken about the cost of an OEM-quality restoration. The cost of an OEM-quality restoration far exceeds the cost of the car when new or the sale price of the car post restoration. This assumes you can actually source OEM parts. Likely as not, this will be problematic and purchasing NOS parts at shows, or on the internet, can be prohibitively expensive. It's why you always want to be the second owner of such a car and purchase it from the guy who spent all the money and had all the work done.
I get the part about favored exterior and interior colors, but the Barrett-Jackson car and this car both have the burgundy interior that, anecdotally at least, doesn't appear to be that popular as an interior color. That said, in the MKIV world, there is a saying, coined by yours truly, that "Condition Trumps Mileage" and color, transmission and other choices we had when the affected vehicle was for sale. I think the same point can be made about MKIIIs, especially where OEM parts are concerned. At this point, if you are interested in purchasing any generation of Supra, extreme due diligence about the condition and need for OEM parts is highly recommended. It doesn't make much sense to spend your money on a car that needs parts that are no longer available.
Back, briefly, to the popular color issue. I own an anthracite metallic MKIV hard top (1 of 19). I mention this because anthracite metallic was so unpopular when the car was being sold new that the popular reference to this color on the street was "monkey shit brown" or MSB. As a result, not too many cars, targas or hard tops, were sold in this color and none after 1994. Now, along with Royal Sapphire Pearl and Quick Silver, it is the third color at the top of the MKIV most desirable colors food chain. Twenty-plus years ago, who knew?
