Yes. I do it all the time.

Also, You want to look at the Cars on http://rr3.wikia.com/wiki/RR3_Wiki:Upgrades_Section_(Classic_Version)

You can find that under the Navigation>Cars>Cars with Upgrade Costs incl. PR.

Find the car in the list and click on the two links and you will get the table like the one above with a PR Delta column included. From that you add to the base PR (Just copy and paste to excel) all of the Upgrade increases. It isn't always 100% perfect as it can depend on order of purchase and internal rounding, but for the most part it is a good way to gauge the cost of a car's upgrades and the performance rating you get in return.
