Welcome to the forum. What did you miss about the Audi. My guess would be the more unfiltered acceleration? I think that would be what I miss about my V6 but I still don't have a Hybrid I can test drive. You should start a brand new thread and post some pics, it would be a big hit!
Thanks for the welcome - I'm usually more of a lurker on forums but actually had an answer to this topics question so figured I'd chime in.
Now have 390 miles on it and just over 41mpg, but I'm on the uphill part of my commute now (home) so when I drive back down the hill it will go back up to 42 or so. During my sole trip around the city where I could measure a leg of about 25 miles or so, I was getting about 50, but that's not exactly a scientific measurement.
If I have time tomorrow I'll take a few pics and start a thread, though I think the uniqueness of owning a hybrid will be over pretty soon.
As for the A6 vs. Accord hybrid, I don't have much regret, but they are pretty different cars. I test drove the accord (the salesman threw me the keys and let myself and my brother take off in it - he didn't even get my drivers license! ) and I was quite surprised at how well it handled, even the electric steering didn't feel that bad to me. And I expected a pretty gutless car, but was surprised at how much get-up it had. This went a long way towards my decision to buy it then and there.
Pros for the a6 were:
* performance - both acceleration and cornering (it was a quatro s-line with 340 hp after all )
* fit/finish and materials - the accord is nice in this area, but the audi really shined here
* trunk size (needless to say the hybrids don't have big trunks)
* MMI control of Bluetooth phone from steering wheel (audi has a nice way of scrolling your phonebook right from the steering wheel, my EX-L does not)
* rain sensing wipers ( I literally never touched them, just left on in auto mode )
* 4-wheel drive (handling in the rain - it rained the day after I bought my car, and I stepped on it and spun the front tires - but that was quite manageable and not a serious issue)
* [Edited} Spare tire - didn't really realize the accord didn't have one until I got home ... The a6 had a full sized spare.
For the accord:
* better bluetooth integration (streaming audio, pandora, etc...)
* most of the features the 7 year old A6 had like keyless entry, etc..
* mileage (of course )
* regular gas (vs premium)
* reliability (assuming honda will win here)
* cost to repair (the Audi was at about 100k miles, and while it had been pretty reliable for me, I could just tell it was getting ready to do something that would cost a lot.
* more room in the rear seats (I'm 6'5" and in the audi only a very small child would be comfortable behind me, in the honda my 6' son can sit there pretty easily)
The big thing here is though - I paid over 60k for the audi (it was loaded) and I paid almost half that for the honda. And the honda has most of the technical gadgetry the audi had that was unique in 2006.
Yes, I'm pretty sure you're the first one here. In fact you're the first owner I've seen communicating anywhere online. Please keep posting about your new car. I'd dying to buy one but the closest Obsidian Blue EX-L that I want is 800 miles away.
If you don't mind me asking (I'm going to ask anyway

) how much did you pay?
I paid list, with the supply the way it was I don't think they were going to do any bargaining. There were supposed to be 2 other parties headed into the dealership to look at it that day - I just go there first

They did throw in a $500 bonus toward the down payment, but otherwise straight list which I think was just south of 32k. Tomorrow I'll start a thread with some pics so I don't hijack this one.
