Some benefits:
Better visibility. With no engine in front of you, the seating position moves forward and the hood line drops sharply to the road.
Better noise. The engine is closer to your ears.
Better rotation. Mid-engined cars have a better polar moment of inertia, meaning turn-in will feel sharper and the cornering limits of the car are likely much higher than what you’re used to. Some more reading on this:

Snap oversteer does exist in any car where the weight of the engine is behind you. Some cars manage this better than others. Basically if you lift off the accelerator while turning, the rear can come around on you suddenly. I’ve pushed Emira on track, and there was a corner where I missed the entry line and made matters worse by lifting suddenly mid-turn (despite knowing well not to) and I definitely felt the rear snap like it wanted to come around on me (but it didn’t, not sure if that was traction control, my correction, or both). The sensation though can be startling if not used to a mid-engine car.
Snap oversteer is something you will experience when pushing your car to it’s limit. We explain what it is, what causes it and how to reduce or correct it.
