Here's another image with cars drawn in. I think I got pretty close to the right scale. This was just using some stock images from the internet, and scaling them based on how long they are supposed to be. Scale might not be perfect, but should be pretty close.
On the left is a Prius pointed nose out. On the right is a Mitsubishi i-MiEV pointed nose in.
The Mitsubishi has the J1772 charging port on the "wrong" side, as it was originally a Japanese right-hand drive vehicle. With the nose in, the charging port is near the south-east corner of the garage.
If the Mitsubishi was parked in the left bay, and nose out, the charge port would be towards the west wall, but that area will be either walking path or have a workbench right against the wall there - not an ideal location for a charging station. One alternative would be to mount the EVSE to the wall, but then have hooks or something to run the cable overhead to the car.
On some other car that we might own in the future, the charging port is likely to be on the front of the car (Leaf style), or the front left fender. Either of those would work better for a car pulled straight in forward in the left bay without the charging cord getting in the way of the driver.
I think that I'll want to have my current EVSE installed in the south-east corner (as shown in the diagram.) I'll also install a 50A circuit for future EV charging somewhere on that west wall. I could even just do that with a 50A NEMA 14-50 (RV Park style connector) as many Tesla drivers right now often use that connection.
