Missing cars in GTA Online [duplicate]

Solution 1:

No your car is gone. I experienced the same thing and the first answer of this question said to call Rockstar games, which I did. I talked to Bernard and credited $725,000.00 back in to our Maze Bank for whatever we spent on our upgraded Turismo car. He can't give back our Turismo car since our garage is full that's why he offered us a credit.

Solution 2:

No, your car is gone. If it would have been transferred to the other garage, the option would have stated "transfer", not "replace".

If there is no more room in your specific garage when you want to store a car there, then you get the option to replace an existing car in the garage. If you "replace" this car, it simply disappears.

To avoid this in the future, transfer the car first. Drive the car out of garage A and into garage B, and it will assign that car to the new garage.

You can swap cars between garages this way as well. Say you have car A in garage A and car B in garage B. If you try to drive car A into garage B and it's full, you'll get the option to transfer a car from garage B to garage A. You can use this to rearrange 2 full garages as well.

To get your old car back, you can try contacting Rockstar support. When GTA Online first came out, I was able to get my Adder replaced from accidentally replacing it.
