here i also tested it:

you can set you'r own radius too

PHP код:

IsPlayerNearSpecificVehicle(playerid, vehicle_modelid, Float:radius)
{
    new Float:vx, Float:vy, Float:vz;
    for(new vi = 0; vi < MAX_VEHICLES; vi++)
    {
        GetVehiclePos(vi, vx, vy, vz);
        if(vi == INVALID_VEHICLE_ID || GetVehicleModel(vi) != vehicle_modelid || !IsPlayerInRangeOfPoint(playerid, radius, vx, vy, vz)) continue; 
        return 1;
    }
    return 0;
}
