In 1980 my wife and I purchased a new 1980 Chevrolet Monza. That car was a horror on wheels to control on the road! It was heavy, had a narrow track, and a relatively long wheelbase....and it came with bias ply tires. Driving in the rain, going around a corner, climbing a hill -- it was a miracle that the car stayed on the road!
So, the first thing I did was go out and purchase a good set of radial tires (radial tires were a new item in those days, but they had a good reputation so far). And THAT did the trick! The Monza was much easier to handle with the new radials, but considering the narrow track, long wheelbase, and the unusually heavy weight it was still a challenge to keep it under comfortable control going down the road.
In a way, although this was the most "dangerous" car I ever owned, it helped me hone my driving skills better than I would have with an easier car to control.
After a couple of years I was able to drive confidently even on black ice (we usually had/still have a lot of black ice on Route 80 in NJ). It got so that I could control that car in deep snow, rain, ice, sleet....you name it. I managed to rack up 169,000 miles on her before letting her go.
