Please find below a link to the spreadsheet containing a list of vehicles available in the Premium Deluxe Motorsport "Configure your own" section. The list does include all base prices, but bear in mind, the cost will increase with additional features and tax is not calculated. On the spreadsheet, you can click on the link attached to the vehicle name, and it will take you to view photographs of the vehicle in question.
