The P1 alone needs 81.0, which takes 120 gold. See the page for that car as to what upgrades I used.

The 911 RSR (2013) is 20% off in showcase discount, so it would cost 480 Gold. It has been on sale 5 times (see List_of_Sales_so_Far, which have either been at 40% (saving you the 120 Gold from the Showcase Discount Price) or 45% (saving you 30 more).  So, if you want the RSR right away, go ahead and buy it.  Otherwise, if you are willing to wait for a sale on the RSR, you won't lose anything upgrading the P1, and you may save a few coins.  Besides, sometimes the P1 is my best car in a weekly time trial, so I'm sort of glad I upgraded it.
