Find/use tire pads on over inflated tires. Heavy wax or glaze on very clean car. Windows open an inch on both sides. Full tank to deny space for condensation, highest octane. Fuel stabilizer. Soft cover. Battery tender attached.
Like the earlier poster indicated, she'll light up perfectly come Spring.
These days, winter just means the top comes off and more track days.
But back from the Chicago days, there was nothing better than the excitement of firing her up and taking the first drive of spring. It was that new car excitement all over again.
Yep, there are folks for whom winter means having to "suffer" with a light cotton sweater on the golf course. Oh, and the occasional scorpion.
But in the dead of winter with the top down I do put the heater or heated seats on..
And I wish (re: the occasional scorpion).. I live on an acreage that backs the desert/mountain, I go "scorpion hunting" at night with a black light.. sometimes none, sometimes many more than I care to see..
No ethanol in it to eat away at the fuel system. Damn, that stuff is evil.
Unfortunately, that's all we have here. I've stored cars for years and never had a problem with ethanol. I add Stabil, fill my tank, change the oil, and over inflate my tires. It's also important to drive several miles to get the Stabil circulated through the fuel system. I stored my highly modded C5 for 15 years using Stabil and it fired right up in the spring.

But still beats shoveling that white stuff..
Ah yes, having to suffer with the need for heat in an open car. (sigh).
The snow is something I can definitely do without. When we had 8 feet fall in three weeks - that's when I started muttering repeated WTF things to myself.
The Car Jacket, a big bag that stays inflated. I have one and my friend that has a split window in cryo storage (not really) has had it set up for years on end.
These types of questions are great and you'll get all kinds of answers, probably most of which are good, some over kill IMO. I'm been storing my "toys" for 20+ years unfortunately because I have liven in northern states where we get miserable winters...cold, snow, slush, etc. Your question on storage and my response, which assumes you have an attached garage or a garage where the temperature doesn't go below 40 degrees F. We've seen 10 below several times over the years and my garage isn't heated but it is attached...never saw it go below 40 degrees.
1) wash and clean the car well, waxing it is your option, nice to do but not necessary if you have the car covered. A car cover or a couple of king sized bed sheets will work AOK.
2) If the oil has more than a 1000 miles on it (standard duty cycle, not racing or tracked), you should change it....under a 1000 miles, not necessary, but it's your option.
3) Full tank of your normal premium fuel. Stabil or other types of preservatives not necessary if your storing for the winter (3-5 months). Condensation very hard to form in that time period (maybe impossible?) with a non metallic fuel tank, which I would believe a Corvette has. Most American cars have had them for years. As mentioned, I have been doing this for years on many different hypo cars and never seen or experienced condensation.
4) Take tire pressure up to 35+ pounds and either use plywood (3/4") boards or go to the carpet remnant store and buy 4 pieces of remnant carpet and park the car in your garage on the carpets. That simply avoids flat spotting which will typically disappear within a few miles of driving the car in the Spring, but I do it anyway.
5) use a couple of small wooden or plastic blocks to prop up the windshield wipers off the front window....keeps the wipers more supple for Spring.
6) put a couple of plates of Decon or similar mouse/rat poison on the garage floor, under the car (one under the engine, one under the passenger compartments) to keep any critters away should they find a way to get in your "warmer" garage. They love to eat the wires and can cause you one major league mess if they start feeding on your car while in storage.
7) last but not least, get yourself a good battery tender or similar charger that shuts off when the battery is fully charged and goes on when the voltage drops, as necessary.
There you have it...done. And if you have any pull on the weather, pray for an early Spring. I do every year, never got it yet!

I think the use of the Sta-Bil is to help keep the fuel fresh and help prevent gum, varnish and corrosion, not so much for the condensation..
Increase tire pressure to 40 psi. That's all that is needed for the tires.
Run the gas tank to near empty and fill with ethanol free gas. If you can't get ethanol free gas, then add stabil to the near empty tank and then fill tank full.
Unless you recently changed the oil, then do it before placing the car in storage.
Make sure all the car windows are up, including the rear hatch/trunk. Open hood and connect float charger or connect to the charging port in the rear of the car, making sure you completely close the rear hatch/truck lid.
Place peppermint oil on the garage floor surrounding the car and on the tire treads to keep mice away. Also put the peppermint oil on the garage floor around the garage door and the door to the house. Also place several aluminum pie plates on the car's interior carpet, front and rear, and place dryer softening sheets in the pie pans. Helps keep the mice away.
Clean out trash in the garage that mice can use to nest in and remove pet food(or put the pet food in a metal container).
Mice can do you car more damage to your car than anything else during the winter storage.
