If you're not bothered about 100% completion. Buying the p1 with r% and upgrading with 180 gold as mentioned is by far the cheapest way through this series. Why anyone would advise to spend 300+ gold on another car I have no idea. P1 with few GC ups  is the cheapest and fastest what through i have just done it.
