my opinion: every car costing GC should be used in at least 3 bonus series or 1 career + 1 bonus AND be the featured car (i.e. fastest car) in at least one series.

It's nice that Zonda R (mentioned previously) is used in 4 series, but it is an also-ran in each. It can't be upgraded to the meet the max PR requirement for any of those series. there are several cars like this.
