2008 Mazda3: B+, very light; good tactical feedback/immediacy
2008 Mazdaspeed3: B, feels heavy/solid, less feedback
1999/2001 Miata: A, it's a Miata
2004 BMW 530i: B+, excellent example of well balanced steering
2003 BMW X3 2.5i: C+, more feeling than a lot of other cars on this list
2007 BMW 335i: C+, meh.
2011 BMW 135i M-Sport: D+, BMW really dropped the ball with this one, artificially heavy, numb, and unpredictable.
2007 350Z: B+, felt appropriately "sporty"
2004 S2000: A, obvious, RWD + lightweight
2010 Gen Coupe: B, felt good, no gripes or complaints
2005 Accord V6: C, weighted up unnaturally, lacked a true feeling of turn-in
2008 E350 4-MATIC: B, very smooth around, only receives "good" feedback while cornering, easy to set the car into the line
2002 RSX-S: A, excellent feel and communication
I left out a few cars, but that will give you a good feeling to where I stand.
