Just thought I would leave this here.
Store/insure any car READ EVERYTHING AND FOLLOW MY STEPS TILL STEP 7!!
I found a way to insure any car into your garage for the patch 1.15
Alright lets begin.
Step 1:
Let a car be impounded by the cops.
Go back into your garage and choose the car you don't need (this car will be replaced).
Step 2:
Go into that car and press RT (xbox) / R2 (PS3).
It says that your vehicle is impounded -> Press B + A (xbox 360) / Press O + X (PS3).
You will get a black screen and then as soon as possible you need to use DOWN on your D-Pad and select a singleplayer character.
It will say: Are you sure to quit blabla? Just Press B (xbox) / O (ps3).
Step 3:
Then walk to the blue circle and replace your car where you did the glitch with the impounded vehicle.
Step 4:
Go to your phone -> Internet -> Legendary motor sport -> Elegy RHB. (Because thats free)
Alright purchase it and replace it with the impounded vehicle.
Step 5:
You can drive in your garage now!
Here is a video if you dont understand my tutorial about it:
THE GLITCH IS NOT DONE YET!
Step 6:
If you can drive in your garage then just press Start -> Playlists -> Choose a playlist.
Just click quit like always before the playlist starts.
Step 7:
Run to the vehicle from singleplayer or from your friend thats standing at the garage door.
Get in the vehicle and thats it!
Do NOT click at JOBS because thats patched by Rockstar.
