Lincoln/Mercury Repair: Whistling sound, lincoln town car, clevand

Question
I was checking out a 1993 lincoln town car with 85,000 miles on it. When we got to 80 or 85 mph, I would briefly hear a whistling noise. They said they had it check out, and the mechanic couldn't find anything mechancially wrong with it.

They said it could be some air getting in the car somewhere.

Do you have any idea what it could be? Any opinions would be appreciated.

Thanks in advance.
