Mileage shouldn't be the biggest concern with these cars. I can tell you, as the new owner of BB #28, this car is flawless in every way. The majority of the 17k miles were put on by the original owner over the first 5 years of ownership. My opinion is condition and history overruling mileage every time.
Good luck with your search!
