Have 1.2.1 version.
Is it posible to make that if the player do not have xRP he cant buy.
Cuz all players just get all vehicles and RP balace is -
Or i need to do it my own?Just do not see where can i fix it.

Sry for bad language.
And ty for help.

In the configuration:

• "Use ServerRewards to buy vehicles": false -- Use ServerRewards point to buy vehicles.

You'd need to set that to true and enable it for each vehicle and set a price for each as well.

"Use ServerRewards to buy vehicles": true,
"purchasable": true,
"price": 500,

but if player have 0 RP balance he still can buy vehicles,just he's balance will be like -31000

The last release addressed this. Check it out and let me know.
