Garage heating options - 2.5 car

[turbotalon1g]

I'm wondering if anyone had any good ideas, I have one of them bullet heaters right now but its on its last legs and I need something better.
I live in a townhome with an association, and I'm hoping to be out of here in 3-5 years.

I keep seeing ideas of a wood burning stove, but I don't really have the room for one.

Thanks
