When it comes to the Mini Cooper Clubman trims, the first choice one needs to make is between the front-wheel-drive model and the ALL4 all-wheel-drive derivative. Both models are available in three basic sub-trims, namely Classic, Signature, and Iconic. The Classic trim is the cheapest option, and you can't add much to it. Move up a trim level to the Signature trim and you can start adding certain technology and styling packages like the Driver Assistance Package ($1,250) and the Premium Package ($2,000). The Iconic trim includes almost everything, bar a few of the advanced safety features included in the Driver Assistance Package. It actually costs less ($850) when you add it to the Iconic trim. The previously-mentioned Premium Package is standard in the Iconic trim. As it's a Mini, there are a host of stripes and side mirror caps you can add to customize the Clubman a bit. These options cost between $100 to $250.
Oddly, for a car most owners would like to customize to their own personal taste, Mini doesn't offer much in the way of packages. There's not much you can do to the base Classic trim, apart from adding stripes and mirror caps. The Storage Package can be added, roof rails, or the 40/20/40-split rear seat, each of these costing $250.
From the Signature trim, you can upgrade to the Premium Package that adds power front seats, power-folding mirrors, and other features for $2,000. The Driver Assistance package adds a parking assistant, and a head-up display for $1,250. The Signature Upholstery package is standard on the Iconic trim but costs an additional $1,000 to the Signature trim price.
