Galen probably told you how many Challenger ragtops were built in total.

Or how many US-spec ragtops were 318 cars.

Or how many US-spec ragtops were B5.

Or how many US-spec ragtops had a white top.

But not any of those in combination.

He'll also tell you how many similar cars are in his registry, but that is his own registry and has nothing to do with total production, US-spec production, or known to exist.
