A4 Avant B9 buying questions

[bill_face]

Hello there, 

 

I'm in the process of trying to find an Audi A4 B9 to buy and have a few trim related questions. A little background. I'd like a upgraded sound system, and quietness (to enjoy the sound system) is high on my priorities. Nice to have are leather seats and Android Auto. Budget will only really stretch to an older model: 2016-2018. I've found an SE with a B&O 3d sound system as part of a Comfort and Sound Pack

1) Are a subwoofer and a spare tyre mutually exclusive (i.e can you have both or is it an either/or scenario)?

2) if I get a basic (SE) trim, apart from the seats and suspension and styling are there any structural differences to the Sport/S-line? Especially as regards sound proofing

3) If I got some S-line seats (I've seen some on eBay) could I fit them into an SE

4) I believe I can get Android Auto on an older B9 with a retrofit kit. Does anyone have any experience? https://integratedautomotive.co.uk/product/audi-mib1-mib2-mmi-retrofit-carplay-and-android-auto-kit/

5) What else does the Comfort And Sound Pack include apart from the sound system

Thanks in advance

Phil
