The owners manual clearly states this car can not be towed with any wheels on the ground or you'll risk damaging the motor, controllers and batteries. When I got my car, there was a big sticker on the windshield that said in International Language - Flatbad Tow Only!
I don't think you'll need a toolkit for this car. It will never break down on you, the motor will outlive the car and you. If any of the wires become exposed, you probably shouldn't touch them especially the Orange wrapped wires which are High Voltage. All the rest of the components are solid state black boxes, no amount of wrenching on those is going to fix the problem.
You are left basically with three things that could go wrong with the car: Flat Tire - there is a tire fix kit under the back seat for this, Dead Starter Battery - that is the one up front, the car won't start or charge if this is dead, you'll need a jump for that or replace the battery, Main Bat Pack Depleted - have the car flatbed towed to a charge point and recharge.
This car is trully that simple. Your first maintenance is at 15,000 miles/24,000 kilometers and it only covers three simple things like get the Bat Pack SOC, replace the in-cabin air filter and something else I can't remember right now.
Like my old motorcycle mechanic told me once about my motorcycle: Change the Oil, Put air in the tires and Ride the Damn thing! Well, I'll modify this for the electric car: Charge the Bat Pack, Put air in the tires and Drive the Damn thing!
