Edit: Updated the spreadsheet. Altered the look of the sheet to be clearer and, I think, easier to read and understand. I've included some instructions for the process, added dropdowns for purchasing Tuning Improvements, and dropdowns for selecting Upgrades. Data autofills a B&W Vehicle Sheet that can easily be copy/pasted into a word processing app for printing. Note: macros for 'Clear Data' and 'Copy Sheet' aren't active in this file.
