Over the years i have had my fair share of cars but two still give me nightmares even now.
The first one was a merc 240D (i have now broken out into a cold sweat), smashing car to drive....... when it started!!!! the first sign of cold weather and it just would not start, it had new heater plugs, new pump, new head and rebore and all to no avail it still would not start and cost me more in taxi fares than diesel. It was parked up till the hot summer and sold. The second car was a Range Rover fitted with a Ford York 6cyl diesel engine, it was gutless, slow, knackerd what handling a Range Rover has to start with and it to would not start in cold weather unless you popped the bonnet, removed the air filter and stuck a news paper in the manifold and set fire to it, it then started on the first turn of the key. I never had the heart to sell it on to someone else so broke it!!! Oh the joys of motoring :-/
