My friend had a similar situation - she wanted her mom's dacha, and her brother wanted the computer and furniture 😅 They just went to an appraiser, found out the actual value of each piece of property, and then worked it out like this: she took the dacha, he took everything else plus she paid him the difference in installments. No court involved, they just sat down, did the math honestly and divided it equally.
In your case it's the same thing - if the apartment is worth more than the car (and it usually is), then either you pay your brother the difference, or you take the car and he takes the apartment plus you pay him. The key thing is to get the exact value through an appraisal first, don't just guess 💰 After that it's easier to come to an agreement once the numbers are clear.
