In the market for a D3

[A8_Tony]

Guys and gals,

I'm in the market for a D3 TDi. Have been looking around and think that the 3.0 is the one I need to go for, but I've got a few questions:

1. SE/Sport - Can someone tell me the differences on these? I keep seeing SE's with Sport seats, are they identical to those in the Sport?
2. Do all of the D3's come with adaptive suspension?
3. Having looked around there are some nice models out here, but there are some with horrendous mileage too. Are there any major issues to watch out for on the high milers?
4. Is there an Audi Multi Media option that allows you to use SD cards in the D3? If there is, when was it fitted from, and is it possible to retro-fit to earlier gen cars?
5. Why are there so few dark colour/light interior cars out there?????
6. What is a realistic MPG figure I can expect from the 3.0? Is it perhaps worth looking at a 4.0/4.2 instead for the extra oomph? I'll be doing plenty of miles in her, so will need to balance power/economy appropriately
7. If I find an SE that I really like, I'll probably go for that, then drop it electronically, and find either a Sport/S8 bumper for the front end. I'm guessing these are a nice straight swap, also taking the lines on the bonnet into consideration?

Thanks in advance for your help
