Oh, how it pains me to read this.
In Finland 335i commands about 15'000 euro premium over 328i. That's 64 358,56 € for a no line basic 335i.
And as if that wasn't enough, there is no business pack for 335i (Business pack is a cheap way to get xenons, blue tooth, PDC (back only), cruise control and folding backseats at about 950 €), so you have to pay the high premium for each and every thing separately, plus anything else your hart desires.
And to add insult to the injury, all the optional extras cost more for the 335i, as even the optional equipment is taxed by the emissions.
