1. Classic Mini
The Mini was an immensely influential and significant car when it was released in 1959. Today, every front-wheel-drive car uses the same drivetrain layout and concept. However, the first Mini wasn’t without its flaws. Apart from being unsafe and rust-prone, the Mini had one major design flaw. Due to a transversally-mounted engine, the radiator was on the left side behind the wheel well. But this design feature left the distributor and spark plug wires without any protection. So during rainy days, water flooded the starting system of the Mini through the front grille.

This left thousands of owners stranded and without any chance to start their car. These are 20 of the most unreliable classic cars that were a thorn in car owners’ sides for years. They all have their innate qualities, yet they also come with some serious flaws, some even with deadly consequences. Hopefully, the car industry has learned some valuable lessons from these cars to protect drivers in the future.
