My worst car.

1969 AMC Ambassador Reverse gear in Auto transmission was horrible.
I couldn't afford the service so i bought three used trnasmissions over the next 6 months from the scap yard before finding the last one which finally worked. No recoup on the countless hours I spent installing transmissions.

1970 2+2 convertible The car was from Ontario and after storing in a barn for 4 years it became a rust bucket. One day the car filled with smoke. When i stopped it cleared. 10 minutes later the cars full of smoke again. I stopped lifted out the back seat and the exhaust had burned clean through the floor and was igniting under side of the rear seat.
It was actually a pretty cool car. I dropped the Olds Rocket 350 and trany into it. (Original motor burned oil) I had to lengthin the drive shaft. the car would idle bom bom bom bom at 30mph. I was fully loaded doing 80mph across the praries making 22mpg. The Ford Mustang 11 driven by my G=friend that had to keep up was filling up 2 to my 1..LOL!!
