Just to play devil's advocate on the behalf of the source of the original quote (Matt Farah) he's no stranger to old cars.
Not even counting all the modern cars/super cars and hyper cars he experienced hes in the episode talking about his experience in both Morgan 3 wheelers (he loved the first gen) and he personally owned a high horsepower Fox body Mustang (live axle?), air cooled 911s, still has a first gen NSX, Lamborghini Countach, older Ferrari (don't recall model), e46 M3 and god knows whatever else.
His opinion certainly didn't come from being sheltered from experience with older cars.
It might have been setup wrong for him sure, but that's another argument. Maybe light cars require more finesse when drivers are more husky but he didn't have similar comments to Morgan 3 wheeler in the review.
