The Z is strictly a fair weather toy for me. I'll drive mine just up until they put down the first salt and or snowfall. Or when the temperatures consistently fall below 5 Celsius. Then it's in the garage until spring with a full tank of fuel with Stabil, battery maintainer, full detail both inside and out, remove Weather Tech mats, plastic vapour barrier sheet under the car on the cement, tires on 2 by 12 boards and cover the car with an ultra plush Sparco cover. Oh, and new oil unless it's been changed very close to storage. I'll back the *** end out of the garage and start it a few times through winter and let it warm up good just to keep things from sticking/seizing.
I envy you guys who can drive these things comfortably all year round or nearly all year long.
