The arrival of my new car – a very fine Mazda 6 – has brought home the smorgasbord nature of modern car equipment.

It’s not long since almost every car would come with the same equipment as its price point rivals – if a Cavalier GL got a rev counter and electric front windows you could bet that the equivalent Mondeo GLX would boast the same (and no more).

But the toyshop mentality with which modern manufacturers go about kitting their products means this is no longer the case. The Mazda replaces my erstwhile Citroen C5 Tourer. Both are in range-topping spec, are fitted with 2.2-litre diesel engines and – once the supplement for the C5’s estate bodyshell and optional sat-nav is removed from the equation – are priced within a grand of each other.

Naturally, both boast the standard-for-the-segment spec that any buyer would expect: air-con, stability control, multiple airbags and a decent sound system.
