2006 BMW 3 Series Sedan 330i 4dr Sedan (3.0L 6cyl 6M)
E90 6MT 330i is a very balanced drivers car
 Previously driving a 1994 325i that was a really great car, in addition to a saab 9-3.  I've been driving my 330i for 5 years  now having purchased with 88k, and now at 174k.  It has been a very reliable vehicle WITH proper maintenance.  I have done the normal items on these cars- water pump, thermostat, control arms, shocks/struts. My factory clutch is still holding fine. I have done rear wheel bearings as well, and adding adjustable rear camber has greatly increased my tire wear on the staggered sport wheels.  I  highly recommend it, it will save you money in the long run.    Lifters can be noisy if you take short rides, or long rides at low rpm... just run the engine above 2k for a few miles to circulate oil up top and you won'd have any problems. I have the BMW performance suspension, on Eibach pro-kit springs, and while it handles beautifully, the ride is a bit harsh on bad roads.  The sport seats are firm, but supportive and do a great job of holding you in place in the twisties.  The ergonomics are "BMW"  That is  to say they are excellent.  The only thing I would change is the distance between the brake and throttle pedal.  My e36 was much easier to "heel/toe" during shifting.  I've gotten used to the switch from right to left with the cruise- I love the simple BMW cruise interface and I don't understand why other manufacturers go with buttons and switches- just a simple stalk works great.  With over 170k on the odo, I wouldn't hesitate to hop in my car and go anywhere.  The 2006 has the controversial "Mustache" grill and I have to admit-I like it.  I don't feel like most BMS's ever look dated- and this design is the same.  Although its obviously not new, it still looks muscular, serious, & classy.  I have my chrome either plasti-dipped or vinyl wrapped for a "shadowline" look.  I honestly can't get very excited about the latest line of 3 series- They seem vague when driving, but hopefully BMW will get their Electric powersteering tuned in a bit better.   The 330i e90 is a rare classic.  Although it doesn't have the power of the 335- it also doesn't have the problems.  Its beautifully balanced and very linear.  I always feel special driving my 330, and I can drive it hard out of corners without it getting out of shape.  Its been a great car.
