I use this like:

pawn Код:

public GetClosestVehicle(carid)
{
    new x,Float:dis,Float:dis2,car;
    car = 0;
    dis = 99999.99;
    for ( x = 0; x < MAX_VEHICLES; x++ )
    {
        if(x != carid)
        {
            dis2 = GetDistanceBetweenVehicles(x,carid);
            if(dis2 < dis && dis2 < 8.0)
            {
                dis = dis2;
                car = x;
            }
        }
    }
    return car;
}

public Float:GetDistanceBetweenVehicles(vehicleid,carid)
{
    new Float:x1,Float:y1,Float:z1,Float:x2,Float:y2,Float:z2;
    GetVehiclePos(vehicleid,x1,y1,z1);
    GetVehiclePos(carid,x2,y2,z2);
    return floatsqroot(floatpower(floatabs(floatsub(x2,x1)),2)+floatpower(floatabs(floatsub(y2,y1)),2)+floatpower(floatabs(floatsub(z2,z1)),2));
}
