BTW this is the first house I've ever had, where I HAD to hang tennis balls in the garage! It was the only way to consistently park the cars and leave room to walk around them. Believe it or not, the Z and the Merc are within inches of being the same length, and when they are parked correctly, there's about a foot on either end of the car. I mean the garage is really small! Kinda funny the Z's ball is about a foot lower and nearly two feet further back than the Merc's.
You probably noticed no 308 in that pic - no room at all. It's living with my brother for now, which really sucks. But we'll get back together eventually.
