I would say BAT unless you could get the cars into some other specialty auction like RM or similar. There is no seller's fee and you could set a reserve on them to protect yourself plus the exposure is unmatched these days. Everyone on earth in the market for those two cars is on BAT.
Also, many cars that do not meet reserve there get sold privately soon after. Nothing to lose if presented well, IMO. Good luck and Happy Holidays.
