I have a 91 2+2 that I drove 365 for 10 years. Ran 4 Blizzaks in the winter months and the car has been flawless even in deep snow (Thank you Tire Rack). The ultimate was having to pull a Saab 9000 with decent all season tires out of a parking lot, he was stuck in about 10 inches of snow.
Driving it without Blizzaks or other ice tires is practically begging for an accident if you have any serious winter weather. My room mate had a brand new 93 convertible Z that slid all the way down our driveway while he slept just due to the driveway freezing up. Factory Z speed Michelins turn to stone below freezing.
