agree. They should be open to all information. Other than that.. I recently switched over to an E39 M5.. love it for the power, room and driving comfort. not to mention, it can take the wife and our newborn no problem.. actually, sometimes the boot is tricky when putting in the stroller. I took 3 buddies last weekend out to Lindsay and they have TONS of room in the back, so I know the kid will be able to grow into it!
That E60 is a rarity in itself. Being NA in all.
Keep searching around cause there re plenty of nice one around.
