Great car. Congrats.
Was at the dealer on Friday having a service, which didn't go well as they damaged my car, but that's a different story. Anyway, I sat in the 1 series and didn't think it felt like a small car. I think I could easily swap the E90 for one, with the exception of it probably not having enough boot space. Maybe when the Kids are older
I'm impressed with the economy - very good for a car that fast.
Have fun!
