The gas gage never worked.
Wind-shield wipers didn't work.
Brake drums made a growly sound when I lightly hit the brake.
Engine overheated and cracked, and I had to install a new one.

Very VERY noisy.
Very small and delicate components.
Couldn't go up hills at all.
Difficult to start if it had been running in the freeway.
Choke valve would occasionally stick.

Don't drive with the oil light on!!
