Bentley and Ferrari are among the car makers that provide the most expensive extras for their already prestige vehicle models.
The marques, which are popular with prestige car hire customers, feature heavily in the top ten priciest car options list compiled by Forbes.
Ferrari's 599 GTB Fiorano costs an extra $22,000 (£11,000) when it comes painted in the car maker's deeper version of the classic colour, Rossa Monza.
Ferrari also has some of the priciest carbon-ceramic brake pad options for its 599 GTB Fiorano and F430 models.
Bentley on the other hand features on the list with its entertainment and luxury extras.
Equipping the Bentley Arnage RL with the rear TV and DVD package will set customers back $20,690. For that price they get two 15-inch LCD screens built into the back seats each with its own DVD system.
The Bentley Arnage R can have its entertainment system boosted to a Level 2 package which features a cocktail cabinet, wine cooler and foldaway worktables for an extra $19,190.
