You can store upto 18 cars including garages from Mike and Frank's home and Trev's strip club, plus customizing cars are free when LSC was purchased at Blaine. Note that there are some cars not seen in online like in IV.

Edit: Just discovered that it allows to store cars on the side of the strip club.
