Like others have said, down talk yourself down like that. …and it’s just a car.
That said, make sure you test a RWD coupe or sedan to experience what BMW is really about. The AWD ones are nice too, but the experience is a bit diluted, especially if it’s a SUV.
The alternatives are selling licenses, selling ads, selling support or selling services. The problem with licenses is that they are not recurring so you have to come up with new stuff all the time to sell more, especially to existing customers. Selling support works fairly well for open source. Services don’t scale when you need twice the staff to double your sales.
