3 stall garage question

Hello guys! We just bought our house back in Sept. The previous owner had the 3rd stall of the garage turned into a wood working shop. There is a wall that is built between it and the other 2 stalls, has a raised insulated floor, and heated. There is not a garage door installed to the outside to pull a vehicle in, just a walk thru door.

We wanted to build a second garage on the property but found out that the city will not allow this. I really didnt want to turn the shop into a garage stall but I dont have any option now, especially with the little **** that is going around slashing tires, over the past month.

So here is my dilemma and wondering what you guys would do if you were in this situation.

Do I cut a garage door in so I can pull a vehicle straight in, which would also require me to pour concrete to extend the driveway to that side. But limits working on the vehicle there since its only 11' wide with the wall still in place.

Or do I take down the insulated wall which has power in it and use the regular garage door to pull a vehicle in? Which would give me more room to work on the vehicle. But would be tough trying to get a car squared up and would probably have to use a jack to move the car over into its place.
