The best thing about A3 is that Audi designed a great looking car that still turns heads, even though it was first introduced in 2003! The interior feel is great, exterior with big grille looks well good.
How many Focuses, Astras etc. we had since 2003?
That's what I like about it.
As for the new MY11 not too much change, which is good - why modify a great design?
Can't wait for the new A3. I'm sure it will stay on top of the game.
The thing with buying an Audi is that you have choice. Each individual can choice which options he or she wants rather than having to pay for all sorts of options that they do not want. For example my SE comes with a MFSW but I would not chose one. I don't like keyless entry. Some people don't like auto wipers etc. With an Audi you get a quality car and a choice of options to add what YOU want. Personally I much prefer it that way. Some of the things that you say are better on the A4 may well be included on the 'new' A3 which will be announced soon. The current A4 is a much newer design than the current A3.
In their home market in Germany the A3 comes with much less standard equipment than UK models and a much bigger options list!
