So you need a V10 to get you 440miles each day?
The US is not that diffrent then europe not all of europe is small and compact.
And pleas public transport is overrated in europe belive me delays whit 20-30min or hours are likely to happen many many times a week on all sides bus,train,subway so getting late to work 2-3times a week is a recipe to get fierd.
I dont see a V10 as a bad thing to be honest, you can brew your own gas etanol that will not only give more horsepower but also 100%green and clean But i do think the dea or ATF!? will ask you about somethings.
