My TT doesn't have seat memory either, and it's frustrating to see that kind of oversight on a luxury vehicle. I'm very pleased with the rest of the vehicle though. If I wanted features, I would buy an Acura or an Infiniti. I choose design and engineering, and hence I bought an Audi. The TT does at least have the HomeLink though.
Anyway, these aren't deal breakers for me on the Q3. The HomeLink may be able to be added later, as an enthusiast mod.
