We have recently added some seats to make our van more comfortable, and the Van is now registered as true 4 seater (For the first time in its life)
Not truly authentic, but practical and safer for this day and age
We removed the rear seat that came from the Van's last owner and put in a Mate's Seat and a double seat
We managed to buy all the seats out of a Toyota High Ace commuter bus (One three seat, 3 two seats, and 2 single seats all nicely cloth covered) and as the package was with all the lap seat belts, the driver's seat has now go a lap belt as well !
We even managed to sell all the leftover seats and make a profit.
