A3 compaired to the A4

[jeepnut]

I'm new here but I have an 02 A4 Quattro with the 1.8t. We leased the vehical and the lease will be up @ the begining of August. We are trying to decide what to by and I see that the A3 is comming to the states. I like the looks of the 2.0t FSI but I am not sure when it will be avalible with Quattro. My question is how much smaller is the A3 than the A4? Also does any one have any idea how the price will compair between the two?

Thanks for your help
