R8 (V10) - can it be used as a daily driver?

[wax lyrical]

What's the average (realistic) fuel consumption in mixed driving?

Maintenance and service costs compared to a Porsche 911 of similar age (2015).

Many thanks for all input and advice.

Upper teens on fuel probably realistic; single figures if you're on it, into the 20s at a cruise. The V10 is many things, but it can't even spell frugal. You could probably nurse it to 30MPG with the cruise on and AC off at 46 MPH, but where's the fun in that?

Slightly less practical than a 911. Long doors, restricted boot/storage. Rear visibility annoying on occasion. More theatrical/special feeling than the Porsche, however.

If you can accept high running costs then I think only you can decide if it will suit you as an every day car. Familiarity might take away some of the specialness, but then there's something to be said for driving something special every day too. I assume you've access to another car for use during breakages, longer service visits etc.
