One of my many weird quirks is spreadsheeting of my car's gas mileage. I track every gas fill-up: the date, the mileage, and the total spent. I started keeping this data with the intention of one day figuring out the long-term value of owning a Mazda 3 versus getting a hybrid (I almost bought a Prius three years ago).

Some numbers from owning the Mazda3 for three years:

• Total miles: 16,462
• Total gas consumption: 533 gallons
• Average MPG: 30.85
• Average price per gallon: $3.02
• Total spent on gas: $1,611.58
  

If I had gotten a Prius, assuming a 46 MPG, I would have spent $1,081 on gas. That's a difference of about $600 spread over three years. With a price differential of ~$8K at purchase time (even with the $3K tax credit), I managed to save significant amounts of money by getting the Mazda3.

And as a general three year review of the Mazda3? I love the thing. Getting it in Carolina blue was a mistake; if I could go back, I'd also get the hatchback. My one complaint about the car is that the angle of the back window causes it to catch a LOT of dust - it gets dirty incredibly easy.

But besides that - it's a fun car to drive (pretty responsive), perfect size for the city, well sized for passengers, low maintenance (no problems thus far), and has managed to be able to transfer almost all the furniture I've bought without a problem! (This streak was unfortunately broken today when I mistakenly assumed the Benchwright Coffee Table from Pottery Barn came in pieces - it comes in one big piece).

(And now I finally have a coffee table!)
