I would take it, and if it's in good condition, you should have no trouble trading it for a natural , and maybe even a sunburst or black.
The burgandy (I assume that's the red you are talking about) is one of the rarest colors, along with sienea sunburst, red and blue. I would put white as perhaps in the same realm as the black and regular sunburst which are less common but not necessarly rare. The natural is by FAR the most common. I wouldn't be surprised if there are more natural t-40's out there than all other finishes combined.
Here's a quote from my infosheet.
"The most common T-40 body finish is a thin satin natural colored finish with the grain accenuated by the application of a walnut colored grain filler. The finish is not extremely hard, but not being gloss, natural T-40’s hide their dents well. Most other finishes are hard polyurethane gloss and stock colors are Black, White, at least two types of sunburst (Traditional and Sienna), Red, Blue, and Burgundy. Orange has also been spotted and Green has been reported, but best evidence is that they are, custom colors, or aftermarket refinishes."
