As others have said, price will be dictated by the prices above and below the 1-series (3-series and Mini).
I'm sure that BMW is well aware the some people have a 30K ceiling on what they will spend on a car (me included, I don't live beyond my means), so it will be important for the 1-series to start under 30K.
I'm less interested in what the pricing will be, as I am about what the final weight for the car will be...
If BMW can get the 130i to weigh in at under 3000lbs and be priced under $30K, they'll have a winner on it hands... Enthusiasts, badge whores, daddy's little princesses, and wannabee ballers will all be in line for one
