Momentum BMW

I bought a brand new 330i from Momentum. The waiting time to complete this purchase was horrendous, almost 3 hours after we agreed on price and terms. It seems that the hard sell for expensive insurance takes precedent over customer satisfaction. After driving the car for a few days I noticed that it was uncomfortable to impossible for me to climb in and out of the driver's seat. The vehicle is too low and I am not that strong and flexible. I tried to trade my car in (3 weeks old, 140 miles) for a new X3 or X5 which are taller and easier to climb. After waiting for 2 hours they appraised my brand new 330i at 30% below the sales price, much lower than CarMax offered. If this reflects the low confidence that BMW places in the resale value of their products, may be all buyers should think twice what we buy. In summary, I own a car that I cannot drive and Momentum was essentially indifferent or hostile to my problem. May be a 2* rating is too high?
