I have just recently completed the story part of GTA4 and had noticed from about half way through ther game there was a garage icon in the top right corner ofthe map near the safehouse,but nothing ever happens with it. I have tried going there with different cars, at different times of the day etc. Has anyone seen it or knows what its there for?

that is for the missions that you did with stevie. if you take a car, a turismo for instince there he will give you cash. A turismo will get you approx. 30-36k if its perfect con'd.

check you messages for ones from stevie, he wants you to deliver a certain car to the garage, its not just any car like the guy above me said until you deliver them all
