Jekyl or Hyde? Which do you drive?

I've been think the last week or so about how two-faced my car is.

It sits quite contently in traffic, doesn't mind the stop/start of the lights, just plods alogn nicely, going witht he flow. Quite easy going. Quiet exhaust sound, doesn't stand out against the daily bustle.

But,

Sink the boot and it's a different story. It becomes a hairy, loud untamed animal, not fit for the social circles of the city life. It scares small children and destroys the peace as it tears through the quiet grassy hills behind the city. Offering thrills and excitement that the plod wouldn't aprove of.

The perfect balance.

So, which car do you drive?
