If you’ve been in the fortunate position to be speccing up a new BMW 5-series recently you may have concluded that buying an upmarket car is getting too complicated.

The new BMW 5 and the 5GT are both cars where choosing options is way more than just deciding what bells and whistles you want, what the budget can stretch to, or even what’s best for resale. It can radically change the way the car drives.

Adding expensive options to the new 5-series - such as electronic dampers and dynamic steering - makes it feel like a different car. Far more like an ultimate driving machine, in fact.

Now you can debate whether BMW is taking the you-know-what by doing this, or whether these options should be available on all models (you can’t add them to humbler Fives). But the fact remains that it’s a headache buying the ‘right’ one when you’re going to be lucky if a dealers has a demonstrator with your favoured engine and gearbox, let alone allowing you to test drive cars with or without these options.
