The Steve H "Alfas are the greatest, nothing else will ever come close", vs Dervy "I like diesels, so I drive a Ka" thread made me think.
What *are* the most important things in a car? [1]
My brother, who does billions of motorway miles reckons it's "Auto box, armrest, aircon and a bloody good stereo", which I can agree / sympathise with.
For me, it's a decent amount of poke [2], aircon, comfy seats, decent handling [3,4], cd / mp3 player, no traction control / esp type gubbins, petrol engine, and an engine with cylinders arranged in a V or flat formation. More than 4 cylinders is a major plus point, as is as much lazy, low down torque as possible.
Reliability is also a handy thing to have.
