***UPDATE*** maybe someone will find this usefull - I only sold 1 dupe and drove out like 8 more out of garage and checked with iFruit if they are dirty ( and they were ).So I have this weird issue: I had a few garages full of old duped issies ( was like 6 months ago ) and now I've decided to come back and sell some, sold one - then got into another one and when i tried to sell it - there was a daily limit msg. This is the first time This have ever happened to me. So i tried to put custom plates on them but I couldnt and the only thing I saw in iFruit app was disappearing car slots like from 12 cars to chose in my online account it dropped to 4 for each time i drove my old dupes out of the garage. I could however put custom and create new ones on other cars. Then I decided to buy a new issi upgrade it and the same thing happened - I couldnt put custom plates on it. I tried duping the old dupes again and its the same problem. Am I in the 1 daily car club? Anyone had the same problem? What should I do?
I have cleaned up ALL of my garages by replacing dirty dupes with new free elegies, I have checked every single garage for possible forgoten old dupes with iFruit ( if the total car selection number decreased I replaced that vehicle ).
My newly purchased issy that i have upgraded was also flagged for some reason and like most of my arena cars so now im sticking with retro customs untill I am sure I can sell arena cars.
After waiting 30hours of 1 daily sell limit I'm now able to sell atleast 2 cars a day.
Don't ever sell dupes that you haven't checked trough iFruit!
