I posted this on rennlist as well...I actually got 23.5 mpg on the way down to LA last week. Mostly highway driving but some Bev Hills and WeHo driving as well. I consider this to be pretty decent as its rated EPA 13 city / 19 highway, according to my car's original window sticker. This offsets the fact that when I am driving in downtown SF I normally get 9 mpg.

Gives one a good feeling to have great gas mileage like that for cruising in a car with driving enjoyment (note, I did not say comfort or pleasure - for that you have the MBs of course) second to none. But I bet when you get on boost it will be a different story. I've read people on Rennlist talk about 3-4 miles per gallon at the track. BTW, I saw your thread on Rennlist as well. Lots of interesting and good response

I've gotten close to 30 mpg on the highway in my 993 TT- sixth gear, 80 mph, flat terrain, constant cruising speed. I've gotten 35 mpg in my 2001 z06 under similar conditions (it would pull about 1900 rpm at 80 mph). My 94 turbo 3.6 was getting 6.2 mpg around town the last time I checked. Gallardo 9 mpg around town. My 914-6 race car gets about 4-4.5 mpg. I'm flying to Birmingham Alabama today to drive the 914-6 Saturday and Sunday at Barber Motorsports Park, the nicest racetrack in the country.

30mpg! Wow! That is amazing! At 60mph on flat terrain I once got 27mpg...for about a mile. Then it quickly went down hill to about 25mpg...then settled in at 23.5mpg.

30 mpg is incredible gas mileage! But the most interesting part was the 964 gas mileage. Since I've read complaints about the 964T thirst factor before (3.3 liter engines) as well, I am starting to wonder whether this is something common to the cars in this model series? My 930 is getting approximately 18 mpg when driving occasionally to the office and back. Some freeway travel and some city driving mixed for this gas mileage. When cruising the AFR hovers around 16, maybe mostly a little over that.
Enjoy the racing!

I havent paid attention to how our 993 TT does in terms gas mileage but probably not good because when we do drive it, we drive it hard. But we only drive it once a week if that because we kind of want to keep the miles low on it. Right now its at 20k...

Once a week for a half an hour should be good to keep the car running well.
No point in letting the car sit endlessly and have the seals dry up etc.

Agreed. No use is the greatest abuse. Especially with a P-car.

thx. Sometimes we drive it more often than others. It hasnt had any problems so far and we've had it for two years. Does anyone know whether the 993 has gone up in value in recent years??

The Excellence magazine has a market update section in which one can find this information. I've only recently started subscribing to the magazine and have the 1974-1989 911 (not the 930 though), 996 and 986 info but not 993 information. Maybe someone else does and will post it here (hopefully).

My own opinion is that (talking about the turbos only) the 930s, 964s and 993s have just about lost all they are going to lose and over time will go up somewhat. The rare models especially so. These air-cooled models are the real enthusiast models and there will always be a demand for them and the supply will dwindle over time. That means prices will go up over a longer period of time. For the short term, and with the new 997 Turbo being here now, there may be a temporary dip in the prices but they'll bounce back again. Hold on to your 993 TT!! What color is yours? Why dont you post some pictures (in the appropriate threads of course), I for one can never get enough of seeing 993TTs.
