Garage parking

[Dan17]

I like to keep one of our cars in the garage, it's a single garage so space is tight, but enough. There's quite a bit of other stuff in there but as long as the car goes in the right position, all is good.

Wondering what you all use to ensure your car goes back in the same position each time? Tennis balls hung from the ceiling? Anything else?

Front to back is pretty easy but what do you use to make sure you don't go too far over one side?

I put some silver tape on the wall that I line up with c.90 degrees to my right - there or thereabouts
