Same with the crown Victoria. My grandpa died a little over 5 years ago and i want the crown Victoria for sentimental reasons. Same problem it wont let me bid on them, could yall send them to me i have 300,000 credits you can have them please help

Its not buggy
Someone is just beating you to buying out
Wouldnt the buyout be 20 million anyway seeing as they are so rare
