They weren't that shit - my old man had one for a bit he said it was like driving a go-kart. He had it 4 years from new and sold it to my uncle he must have run it for about another 6 years with no troubles.
Bidding has gone quite high on that one linked to, up to £900 with a day to go...okay it only has 4K on it but it doesn't start! Not worth that kind of money, I would give £100 tops.
The Allegro gets slagged off too much - they were quite well built and good engines too. The later ones were better. Anyone recall the Triumph Acclaim? real old man's car that one but again reliable and you could buy them cheap in the nineties, always low mileage one owner from new and kept in a garage. Bargain motoring.
