2. Visual method, with Google Sheet
   1. Alternative, to create the information visually, this can be used: Google Sheet Car data
   2. As anyone can edit the above sheet, to avoid conflicts, if you have a Google Drive, I would recommend you save a copy (File > Make a copy...), which will save the Google sheet to your own Google Drive, for your own personal use.
   3. Anyone can edit the above sheet, even without a Google account.
   4. The Google sheet also creates the data for the RR3 Wiki:Upgrades Section (Classic Version) page, killing two birds with one stone :)

For upgrades including PR values, please see the project page RR3 Wiki:Upgrades Section AUDI, please be aware that PR values can vary depending on the upgrade order.

Note: The only way to capture the PR data properly is as follows:

1. Cloud save
2. Capture and complete one upgrade at a time, from base
3. Pay gold to complete any R$ purchases
4. Check the data and complete the next upgrade, one at a time
5. Capture & complete all R$ upgrades before starting upgrades
6. Double check the data captured actually equals the R$ upgrade data (Base PR + R$ upgrade data = Max PR w/ R$)
7. Capture the car data for PR Max cash, (PR, Top Speed, Acc., Braking, Cornering, Cost, Parts) - change the device's settings between imperial and metric (Settings > Display > Display Speed: MPH | KPH) for top speed MPH/KPH and braking ft/m, do not use a calculation.
8. Continue to capture the remaining data, as before, one at a time, pay gold to complete R$ upgrades
9. Once all data has been captured double check the data captured actually equals the fully upgraded car data (Base PR + upgrade data = PR Fully upgraded)
10. Once the car is fully upgraded, capture the car data for Max PR w/ , (PR, Top Speed, Acc., Braking, Cornering, Cost, Parts) - change the device's settings between imperial and metric (Settings > Display > Display Speed: MPH | KPH) for top speed MPH/KPH and braking ft/m, do not use a calculation.
11. Cloud restore (to get all the gold back)

It is very time-consuming!
