Market Update: Could This Be The Next Callaway C4 To Fetch $100,000?

The iconic Callaway twin-turbo conversions were available through select Chevrolet dealers as Regular Production Code (RPO) B2K from 1987 through 1991 and brought the Corvette brand to the next level of performance with styling upgrades that rivaled the best the European marques offered. The Callaway C4 had the exclusive and rare boxes checked, with just 510 special RPO B2K examples produced during this short five-year period, and these twin-turbo monsters still hold the distinction of being the only engine package produced outside of GM to hold an RPO code. The unfortunate passing of Reeves Callaway just last year makes these rare Callaway Corvettes even more collectible.

All of these factors prompt CorvSport to keep an eye on the Callaways, so when this near $100,000 example recently popped up on a popular Facebook for sale page, it was only natural for us to take a closer look at the market. Below, we have some notable sales from Bring a Trailer and Mecum, with a quick look at the C4 title holder, a 1991 Callaway Speedster that sold for $148,500.

First, let’s examine the seller’s listing, which led us to this interesting look into the Callaway market.
