A BMW M8 Gran Coupe lease deal is the best option if you want to enjoy the refinement and power of the M8 but with some added practicality and space. It has a 440 litre boot, with folding seats for more storage if you need it. If you have regular rear passengers the extra doors and larger seats will keep them more comfortable than other M8 versions too.
If practicality is not your first concern then look at the M8 Coupe for driving experience, or the M8 Convertible if you like to cruise with the roof down.
