Not a place you'd want to be, abandoned by faulty engineering or unfair wear and tear, stuck on the hard shoulder while all of life passes by, ignoring your stranded plight. Based on my occasional and unscientific observations it's the continental motors that seem to end up there most of the time. The French models in particular, those complex design masterpieces by Renault and Citroen, seem most prone failing their owners at a critical time - I don't believe that anybody in the Hollywood set would consider driving one either. I did however clock a burning Mercedes roadster on the M40 last Wednesday evening, so you can never tell, prestige motors and reputation may not count for that much really.
Renault Clio, Renault Megane, Renault Espace, Renault Scenic, Citroen Xara, Citroen Saxo, Colt Spacestar, Fiat Brava, Fiat Punto, Fiat Coupe, Toyota Corona, BMW 3 Series, Alfa Romeo 175, Rover 25, Rover Metro, a Bentley I once saw, Ford Mondeo, Ford Escort, Kia anything, big silly Jeeps, Mercedes 180s and mobile cranes. Now I'm really bored with this...but I do feel sorry for all motorway breakdown victims.
