I'm coming from a 2000 Mazda Miata, which is my first and only car, purchased in 2010 with 45,500 miles. Six years, zero speeding tickets, a rebuilt engine, and 90,000 more miles and it's time to retire the Miata from its duty as a daily driver. The Model S is going to be my new daily driver with the Miata sharing weekends and track days with my Suzuki supermoto and Ducati superbike.
My wife has a 2008 Acura RDX that we plan to replace with an Audi Q7 next summer, unless we come around to the idea of an X (we're not sold on the styling quite yet).
We're still waiting on our delivery date, but it should be mid-September. We're getting pretty excited!
Once you start driving the S, you will soon forget about the Q7 and get yourself an X
