Great stories..
I owned a '66 Toronado from 1993-'96. Great car, drove it in the winter as well. Finally spun a bearing -- when I pulled the motor and trans to part out, I suspected the PO had rebuilt the drivetrain, so I figured it had over 200k miles.
In 2000 I bought a '70 Toronado GT (Olds claimed 400HP, same cam as the 442, higher stall TC). That 455 had some serious torque. I liked that car much more than the 425 powered '66. It was fast too -- you could nearly peel the tires off. Some dingbat ran a light and hit me summer of 2002. I parted it out and a Cutlass guy bought the motor for a street rod project. The car had 120k miles on it, used no oil. I never had a problem with it, with exception of an annoying trans fluid drip.
I also owned a 307 powered Delta 88 (winter beater). The PO had used it as a tow vehicle and it was originally a rental car. By the time I sold the car, the motor was tired. My buddy bought it from me for $300 and managed to drive it another 2 yrs and 30k miles w/o a hitch. Then the trans went out, dang 200M trannies.
