Re: Looking to buy a 2004 / 2005 Limited Coupe
I accelerate conservatively but I see 27-28 mpg highway consistently, although I drive 75-80 with frequent spurts to 90-100. I came back from Detroit to Grand Rapids one night following some bear bait at 95-100 for an hour, and still saw 26 mpg. Manual vs auto is a preference.
I also use midrange almost exclusively. Premium is not just recommended - it is required. But I have not had any problems at 28k with midrange and I've tried a few tanks of premium...it did not make a noticeable difference.
Besides the chrome-like trim, I believe the limited only has the high-back seats.
You won't enjoy the manual rear-view mirror or the crappy cup-holder.
If you live in the snow belt, keep the TT for winter driving. My A6 is unbeatable in the winter and I would never consider driving either Crossfire because of traction and salt.
