The Continental was much heavier than a Mustang and heavier than a Thunderbird too. It was also front wheel drive, which may have had an effect. In normal driving I never had a problem with the Continental, but I like to test the limits of my cars in the rain and that Continental was certainly harder to brake in the wet past its limits than were the Mustangs or Thunderbirds. I don't remember all the details, we're talking decades ago, but for anything other than straight line breaking I preferred cars without ABS at the time. Even if ABS ostensibly helps you steer.
