I did have an account with BOA already (home mortgage), but I think the rates apply for anybody. They currently have 3.09% up to 60 months, but my loan stated that if I purchase more than $25,000, I get a 0.20% deduction = 2.89%.
And yes, we did pick up the x5 last wednesday. I originally had an X5 on order without premium sound but found out that the x5 35i now only has the Base Audio sound system (started in 2010). Only the x5 50i comes standard with HiFi (676) loudspeakers. So we spent the extra money to get the premium sound (677). It definitely makes a difference compared to stock (loudness and the ability to customize the equalizer).
The x5 only has ~300 miles right now so I still cant comment on the engine performance. I do have to get used to the hearing the turbo spool up though... it's definitely a different sounding engine compared to my M3's V8
