I think geo's are wonderful to learn on, from my experience so far, they have (even the 93) many components you see in newer vehicles, and components from older ones as well. I have compared the mycarworks geo to other newer vehicles, and there are a lot of similarities when it comes to the setup of the car, and how the engine is mounted and such.
I am still new to mechanics, but from what I have learned so far, they are worth the money.
