Two quick C6 Q's
I've been reading this forum for a while and I gearing up to get a C6, probably a used 05 or 06 in a few months. Two quick questions,
1. I'm tall, 6'7" I've done a search on headroom, but not totally convinced when I hear comments like "I know a guy whose 6'6" and he fits OK." Any personal comments about headroom in the C6 coupe?
2. Gas mileage, I've heard accounts of high teens to mid twenties for all-around driving. My question, which has better real-world economy MN6 or AT6? I know, I know, the vette is a sports car and should be driven like one, YMMV, but I'm just curious to hear a few personal accounts.
Thanks.

I can’t speak to the headroom question as I am under 6’. But with my 07A6 I consistently get between 19 and 20 on my daily commute which is stop and go surface streets, about 50 miles round trip.

I'm 6'4 head room and leg room are very tight for me. with seat all the way back my knees are 1-2 inches from the dash. With the seat moved down and reclined to give me the most head room I can still hit the back of my head on the area behind the roof panel. I'm still pretty comfy in it though, and just made the 1000 mile trip to Tail of the Dragon w/o a problem.

The transparent top will have the most room for you so it might behove you to get either it or the 2 top option. "Usually" a standard transmission will get the best mileage over an automatic. Most automatics are now very close to manual transmissions for mileage since improvements in lock up converters and such. My in town mileage is usually low 20s and highway at low 70s speeds will net me 29-31 with a manual transmission.

I'm only 6'1' tall so I can't address your headroom issue. But, I can tell you that without a doubt the A6 (when left to shift for itself) gets much better mileage.
Maybe, it's my driving habits -- I come from the old school of driving BMWs where it's best to keep the RPMs in the range of 2,500 and up -- and when I drive an MN6 or am using the paddles on my A6, I tend to shift at the higher points. Note--> If you never shift before 2,500 RPMs, you will never have a problem with CAGS.
But, the cold reality is that the A6 chooses its shift points to keep the RPMs in the 1,200 to 2,000 range in normal driving and this 1,000 RPM difference does have an impact on the MPGs. But then, if MPGs had been a big concern for me when buying the car, I would be driving a Prius.

Regardless of the milage factor, go for a late year '06. There are many dealers out there with new '06 models left that they would dearly like to sell.

I'm 604/225 and I have about 2 inches of headroom with the solid top. I also have the clear roof, but have not put it on the car yet. I filled up the tank for the first time today and did city driving only. When I got home, I was averaging 20.2 with the A6. I was very impressed.

At 6'7", there's a very good chance you won't fit at all.
I'm 6'3". My friend is also 6'3", but with a 3" shorter inseam. I fit comfortably in the car (but if I were any taller, it would be a problem). He can't fit without slouching. You need to sit in one and see for yourself.
Also check if the back of your head whacks the roll-hoop behind the seats. I've nearly knocked-out my tall friend under hard acceleration.

I'm 5'7" so I can't address your headroom question. I will say that the dash is close to the knees regardless, that's just the way the dash is designed. If your feet are on the pedals the dash will be 1 to 2" off your knees, tall or short like me.
As far as mileage, I get 15 to 16 mpg per tank in my daily driver Z51 MN6. I have a short 15-mile roundtrip commute that is a mix of city streets and congested, slow and go, freeways. I tend to drive fairly conservatively, shifting around 2500 rpm and running steady around 1500 rpm.

Any particular reason to buy a leftover '06 model?

The '06s also have some advantages over '07s: an off switch that takes effect right now (essential for any 400hp machine I'm getting into), an underhood lamp and a hatch handle (both victims of third-year cost-cutting), all the Z51 coolers promised by the brochure (secretly shortchanged in '07), low-bling sill plates, a steering wheel unsullied by the indignity of radio buttons (optional in '07), no garish two-tone seats with unsubtle Corvette logos (optional in '07), and of course the availability of that greatest of colors, Daytona Sunset Orange Metallic (no longer available in '07).
'07s do have ever-so-slightly-better-made wheels (Italian Speedlines), a bigger glovebox, and a significantly better warranty (for whatever that's worth, seeing as you have to take it in to a Chevy dealer for warranty work).
And of course, the roofs of '05s, '06s and early '07s tend to fly off, but that's covered forever under a recall campaign.

I drove from Maryland to Atlantic city and back, went 422 miles before the low fuel warning came on and it took 16 gallons. That's about 26 MPG. I was very happy with those numbers. I may have driven a little spirited once or twice.
