Cheap bass or stringed neck in the car for practice?

I'm a very busy person but I still find time to practice in a proper setting. I'm sorry but I find the idea of practicing in my car, positively repugnant but hey, if it works for you.....

I have been thinking about that for a while.

Maybe this will do: Ibanez Mikro bass.
