is 08 A3 gonna be sameas 07 in terms of design...i heard that 08 will have a facelift but im not sure.

 

There's been some talk of a facelift for later in the 08 model year. No one knows for sure yet exactly when.
And the pics I've seen are very very minor changes, not worth waiting for.

 

I've been looking at '07 and '08 A3s. Here's what I've found...
No difference in overall appearance aside from some style changes for the optional wheels.
For 08 there is one color change (Ice Silver replaces Light Silver), TPMS (Tire Pressure Monitoring System) hasbeen added, 2.0T model has driver information display added, Sirius and auto-dimming mirror with compass have been added as standard to 3.2model.
For 08 there is an iPod integration option.
Plus there is a new S-line Titanium package.

 

There was an ipod integration earlier than 08, I just believe it's a little different now.

and don't forget that s-line package now includes a power drivers seat.

 

Facelift on the 2009 model, next gen A3 will be a 2012 model.
