This is something I go through every 4 to 6 months - small car (Golf) vs more spacious car (A4 Avant, A6, RR Evoque, etc.).
The minute I stop the back-and-forth is when I buy. Personally I don't find the A4 sufficiently spacious, especially in the driver's compartment. The Evoque is fantastic and the A6 is awesome. But they don't have the small-car maneuverability.
Sorry you bought and changed your mind. Good luck to you.
If I had the money or need for a second Golf (or a place to put it), I'd consider a trip to Cinci. Instead, I'll keep driving my wookiee. GLWS and free bump for you.
