$40 in gas?????????????????
Don't kid yourself. Assuming it got 50mpg and the cost of gas was $0.80/liter, Streets and Trips calculates the cost to around $130 (still not bad) traveling the shortest rout coming back through the US.
Also a brand new car that hasn't been broken in yet will not get that type of milage, and cars rarly, if ever, get the mileage that is rated by the EPA in real world driving.
