I've been driving our 2009 Nissan GT-R every day for the last three week as we sell it on eBay Motors and Mota.com. It's not my top pick for a daily driver but it is surprisingly practical and comfortable once you put the suspension in comfort mode.
I've even seen the fuel efficiency rise slightly to 19.5 mpg on the last tank from a lifetime average of 17.4 mpg (although I know it's kind of crazy to even talk about fuel economy in a car like this). But the fact of the matter is that, unless you are rich enough to save the GT-R for weekend jaunts, you will wind up driving this car around town and to work. And it definitely fills the bill there too. Just don't ask anyone to sit in the "back seat."
I have to agree with what they say in this hilarious Youtube video, "It was supposed to be the car of the century! You could own the track but you could still take it to go shopping."
Meanwhile, at this writing, the bidding on eBay is up to $50,100 with 5 days to go. The reserve hasn't been met but it's getting close. I'm happy to say we are now above the price that Carmax offered us for the GT-R.

Haha, "I'm going to sue the pants off Nissan".

But you'd know that Carmax would buy it from you.

It's never too hard to beat a Carmax offer...

Whether a car is a daily driver depends more on the driver than the car. Drivers can be whiny about NVH or wish for the excessively visceral experience of a track car on the road. So when I hear about whether a car is a "daily driver" I look at the writer / speaker more than the vehicle.

You have spent $8,000 dollars servicing this car. So, yes, it is crazy to talk about fuel economy in a car like this. I can't say I wouldn't love to have a GT-R as a daily driver, but it wouldn't be because I couldn't afford a second car.
