There a lots of things to be weary of, but I assume you mean wary.
You may need new tires.
Depending on the humidity where it was stored, there may be corrosion inside cylinder walls and heads, and above the oil line in the transaxle. Change engine oil, coolant, and transmission fluid. If the engine is running well and the transmission is working, count yourself lucky.
Brake friction surfaces may be corroded, but those can often be resurfaced. Brake fluid should be changed.
You'll probably need wiper blades.
