1994 Ford Escort station wagon (a babe magnet if there ever was one :D)
130,000 miles and still getting 25-28mpg in the city. I drive about 60-70 miles per week.
1997 Hyundai Accent
31 mpg and I drive too fast so it would probably do even better at the actual speed limit.
93 Toyota pickup, 25 mpg. My daily driver, my commute is about 35 miles a day.
97 Ford Taurus, 24 mpg, wifes car, a tank of gas lasts her a month.
66 Pontiac GTO, 10 mpg on a very good day and she burns premium unleaded. I haven’t driven it as much this summer as I anticipated. I was planning to driving down for Hot August Nights in Reno but I couldn’t see a $300 gas bill to do it.
2005 Mini Cooper S -
25 mpg city, 32 mpg highway. This would be better if it wasn’t the supercharged model.
1990 GMC Safari conversion van -
Dunno - it only gets used for hauling dogs and building supplies. I filled the tank at the beginning of the summer; it is still half full. I would guess 15-18 mpg.
My bike -
Infinite mpg 
I am considering commuting to school this fall; round trip is 26 miles. My SO has commuted to his job (round trip 16 miles) for years.
Please insert the work “bike” in front of commuting/commuted above. Of course we already commute daily; but have turned to our bikes for more and more of our transportation needs lately.
We get 25mpg out of our '93 Le Sabre. That’s a pretty vast improvement in 10 years.
BTW, it’s for sale.
I’ve been spending about $5 to $6 per day on gasoline since I started keeping track last summer.
2000 Dodge Stratus - 4 cyl - not sure but I think its 2.4 l - around 30 mpg. I set cruise control at 65 mph.
1987 Jeep Commanche - 4.0 l, 6 cyl. - 5-speed manual - 25 mpg - again I drive 65.
Really? I have a 2003 and I get between 36 and 38 miles per gallon, although I have a stick shift, which supposedly helps a little. I also drive a lot of miles until optimal conditions for good gas mileage: long drives with little or no stopping at 50ish.
i’m visiting my brother in Germany, and gas is about 1.25 to 1.30 euros per litre …
::pauses to crunch some numbers::
that’s over $6 per gallon.
There was a Bloomberg News story in the local paper yesterday that cited average prices in the G7: Canada $3.27, Germany $6.17, UK $6.09, $5.98 in Italy, $5.84 in France and $4.45 in Japan. They said prices were up between 8.6 and 14.7 percent over last year, while U.S. prices were up about 35 percent.
To the OP: I ride the bus to work (and monthly pass prices haven’t gone up - yet; I don’t use my car much, but am starting to give second thoughts to trips and am trying to bundle them together even more than usual. I have a 2001 Nissan Sentra, but have no idea what my mileage is.

I ran some statistics based on page 1 of this thread.
The average MPG was 26.7.
The median MPG was 25.
The standard deviation was 9.7 MPG.
The highest MPG award goes to Grelby’s 2003 Toyota Prius with 48 MPG.
The lowest MPG award goes to StuffLikeThatThere’s 1-ton Chevy work truck and its 7 MPG.
Note that our average MPG of 26.7 is slightly above the US fleet average of 25.2 [1], I would guess because we own less large trucks than most of the population.

My last car was a '98VW Golf, even after being “chipped” and with an aftermarket exhaust, it got about 33MPG. All that at 190K miles, when I finally got a new one.
My current car/truck, an '05 Subaru Baja, gets 25-26MPG.
We own a Honda Civic hybrid, a 2004, I believe. When I drive it, I get about 45 mpg, but when Mr. brown drives it, he gets about 50 mpg. He commutes a long distance, and seems to have perfected the skill of wringing the most mileage out of it. Of course, I have a leadfoot. I wonder what people think when they see the hybrid passing them at 87 mph on the freeway!
'97 Aerostar- my commute is around 26 miles one way, and I get around 22 MPG most of the time.
My sweetie drives a 2003 VW Jetta TDI - he gets 48-50 MPG and his commute is 58 miles one way. He’s also got a Royal Star, but I don’t know what it gets, and he rarely rides it.
I drive a 2003 Honda Accord that gets about 20 mpg in city driving and 30-34 on the highway. I got around 33 mpg driving from Florida to St. Louis averaging about 80 mph most of the way. Interestingly, I got about 30 mpg driving around Fort Myers this summer. Even though it was a lot of stop-and-go traffic, I think there was enough 60 mph driving to make up the difference. My commute in St. Louis is about 3.5 miles.
I have three Ford Crown Victorias. If you do the research, you will discover that the Crown Vic has consistently been one of the safest, most reliable, longest lasting cars for the money for many years. If you can handle being made fun of by your friends and family for driving an “econo-barge”, you’ll have one incredibly practical car. But one thing that really bothers me is that my 1992 CV gets 19/27 mpg according to the EPA (in my experience, 15/20), and my 2003 CV is rated at 17/25! The gas mileage actually got worse with time, and based on my driving experience, the '03 gets about 13/18 mpg. Ford finally figured out CV owners dirty little secret, and gave the engine a 25hp boost. See, most of us don’t buy the car because its cheap, safe, roomy, and reliable, but rather for Geriatric Street Racing. Cowabunga and hold on to your teeth!
'96 Chevy S-10, four cylinder, 5-speed manual: Gets from 29.0 to 30.5, depending on how much I run the A/C.
'96 Honda Odyssey minivan, gets 25 on the nose, every time. (We do virtually no city driving.)
'93 Ford-New Holland tractor, 10 speed manual transmission, diesel engine. Who knows? 
Horses: One day’s ride per acre of pasture. If gas gets much higher, Ol’ Dan may start getting more use.
