These days I'm not sure if "RARE" is an accurate depiction of any model.
Just a few short years ago, the UT 1998 White Corvette was extremely hard to run across on eBay and when they did, they fetched a pretty nice penny. In the past month, I have seen a few show up ebay and the average price has been approximately $30.
I bought the one pictured below for $65 off ebay last year and then Tom D found one locally on clearance for $28 shortly after and shipped it for me. So "RARE" doesn't last long in this hobby.
The white/red and wht/red have always been hard to run across.
However, the yellow/blk combo is an Limited Edition version, its a 2000.
There is a Torch Red with Saddle Interior that *rareLY* shows up ebay. Its a 1998, not to be confused with the 2000 Magenta Red that is very commonly found on eBay.
Heres a picture of the white/red combo showing the carpeted interior.
