Buying a Jaguar is complicated, but in a satisfying way. As you're finding out, or perhaps you know already, once you've picked the model you want, you then need to pick the grade and then the engine, and then the options.

This luxury of choice applies to Jaguar's newest small SUV, the E-Pace, too. You can even get an entry-level 'blank canvas' grade.

The E-Pace S P300 sits just above that base-spec car, which is what the 'S' means, but the P300 engine is the most powerful petrol powerplant you can ask them to put under the bonnet.

So, could this combination of an almost entry-level E-Pace with the top-of-the-range engine make it the smartest choice possible?
