Thing is, Having driven many old cars...... they suck.
They are uncomfortable, Unreliable, difficult and just not as much fun to drive as a modern car.
They have a nostalgic quality but for an actual drive, they just plain suck.
In the case of the 250 GTO, being impractical is sorta the point. It was built for the track with few compromises. Just think what a fun filled weekend you could have balancing it's 6 Weber carbs
