Oil cooler leak 2014 Chevy Cruze

As stated above, my car has an oil cooler leak so my coolant is slowly leaking out over time. The cost to fix it would be more than the car is worth, so we decided to get a new car and trade it in. I need to make a 40 minute drive with it from the mechanic to the dealership tomorrow. How risky would it be to make that drive?
