Make sure you try out the Infiniti G35 Coupe 6-speed also. Not quite as quick or nimble as the 350Z Track edition, but much more comfortable as an everyday vehicle.

And on the topic of miles: a few years ago my car was stolen and I ended up putting the entire repair bill (over $17,000) on my credit card. The finance company wouldn't endorse the insurance check without examining the vehicle, and the body shop wouldn't release the car to be examined without full payment. Total Catch-22!
