Those were the days Peter!
They produced C30,000 there over 6 years,but their demise was started by that much larger saloon the Mini in 1959!!!!
The Plus model had bumpers(+ overiders!!),wheel trims,heater(fart in a thunderstorm type),and a door pocket!You can imagine what the basic car was like as even the plus did not have-seat belts,interior light,trip meter,windscreen washer,cigarette lighter or clock.The only luggage area is on the parcel shelf or a picnic basket mounted on the rack you could fit on the rear.
Those really were the days!!!
