BC on the Wolverine and Blue Water have the faux leather seats fairly often, but there are a couple cars that still have the cloth. I like that the lighting tends to be more subdued, as well.
Every so often, I get the BC car that has the horrible bright lights and no luggage racks. I hate that car.
Other posters were correct about a free non-alcoholic beverage in addition to unlimited coffee, tea, and water. The newspapers used to be left on the seats, but all of the attendants I've had over the past couple of years walk through the car and offer one in person instead. They also use that time to greet us and explain the drink system.
I notice this happens more often on the trip out of Chicago, though, when we're sitting there waiting for Coach to finish boarding. When I board in Kalamazoo, the attendant is usually busy serving customers. Sometimes they pop into the car to greet anyone who just boarded, but more often than not, they have a long line and can't leave.
I checked prices for a weekend round-trip between Kalamazoo and Chicago (approximately 2:15 trip). I chose a weekend one month in the future and used the regular Adult fare.
The lowest cost is $112.
If I choose other times, the cost creeps up to $160.
I used to ride in BC exclusively because 1) I always had enough points and 2) I hated the mass hysteria style boarding process they used to use for coach. Now that they have the Legacy Lounge and a somewhat respectable boarding procedure, I'll probably go back to riding coach. It doesn't make any sense to me to pay $112-160 for a two-hour trip.
