      nfs = "nfs";
      if(VehicleInfo[vehicleid][Price] == nfs)
      {
      format(szMsg, 128, "ID: %d, Price: Not For Sale, Owner: %s", VehicleInfo[vehicleid][Id], VehicleInfo[vehicleid][Owner]);
      SendClientMessage(playerid, GREEN, szMsg);
      }
      else if(VehicleInfo[vehicleid][Price] != nfs)
      {
      format(szMsg, 128, "ID: %d, Price: $%d, Owner: %s", VehicleInfo[vehicleid][Id], VehicleInfo[vehicleid][Price], VehicleInfo[vehicleid][Owner]);

Use the following code:
[pawn]public OnPlayerEnterVehicle(playerid,vehicleid)
{
      if ( !IsVehicleForSale(vehicleid) )
      {
         new id, szMsg[ 128 ];
           id = GetPlayerVehicleID( playerid );
         format( szMsg, sizeof( szMsg ), "ID: %d | Vehicle owner: %s | Shared: %s", id, VehicleInfo[ id ][ Owner ], VehicleInfo[ id ][ Share ] );
         SendClientMessage( playerid, COLOR_GREEN, szMsg );
      }
      else
      {
         new id, szMsg[ 128 ];
         id = GetPlayerVehicleID( playerid );
         format( szMsg, sizeof( szMsg ), "**pm >> You have $%d? Type !buycar %d", VehicleInfo[ id ][ Price ], id );
         SendClientMessage( playerid, COLOR_GREEN, szMsg );
      }
      return 1;
