I just went thru this dilemna with my girlfriend. We looked at everything I thought she would be happy with. She turns in her 3 series today and was very disappointed with all the problems it had (in the shop 11 times in a year and a half)....so no new bimmer for her. I liked the Lexus 350 alot, but it was too small inside. She wanted a four door that would be okay to haul around 4 adults and have a decent amount of luxury. She ended up buying the new 2007 G35 S model. Very nice car.....306hp rwd and too many niceties to list.
