Soldato
It was a 125 mile round trip, 125 miles @ 40mpg if you want to try and work out the petrol cost (unleaded), and 3 hours of my time.
No idea what a taxi would have cost.
Around £20 (16p a mile) in cost of petrol alone, or £56 (45p a mile) overall. Taxi woukd have been more in any case. I mean it worked out better for them. Wouldn't lose any sleep over it.
