The most dangerous car I owned was a 1979 Pontiac Trans AM, similar to this one:
Mine had no decals, and the wheels were trimmed in gold paint accents. It had the 403 OLDS engine. I bought it used, and shudda left it on the lot! The engine had been mildly hot rodded, and it was truly wicked, but it didn't like wet pavement, at all.
The first thing that happened after I bought it, was the headliner fell down into my face on a nice little 70MPH drive down the highway one day. Pretty freaky. I ripped it all out and placed it in the nearest garbage receptacle. The heater fan quit, which didn't help defrosting chores any, the passenger door took about fifteen minutes to get it latched, which made me always leery that it might pop open on the highway. The water pump exploded one day on the way to work, and covered the windshield with brown water! Another pretty freaky!
The most dangerous thing that happened was in big city driving, at about 45MPH, the master cylinder gave it up. I was coming to a traffic light that was red, and tried to stop, to no avail! I was about twenty feet from the newer Mercedes in front of me when the light turned green. The driver of that car must have seen me coming, because I've never seen a Mercedes burn rubber like that one did! I coasted to a stop, and called the tow truck! The last thing that happened before I traded it off, was the motor mount broke, the engine torque-jumped, pulling the gas line loose, spilling gas onto the exhaust! Pretty freaky! Another tow truck was involved in that! I traded the car off on a Friday....the dealer sold it the next morning....and that Sunday I saw it on a tow truck. The following Monday, I stopped in and inquired about it, and the dealer told me the new owner threw a rod through the block! Pretty freaky, again!! After six months of this adventure, I traded it for a Chevette, and I'm glad I did!!
Remind me to tell you all about the other dangerous Pontiac I owned, someday!!
