Hi Folks

I am 48% through the Lexus showcase series, and 4 trophies away from unlocking the Porsche sub-series.

From looking at the title screen, there seems to be a lot of cars available in the Porsche series. Are these unlocked in the same fashion as series with fewer cars? Do I need to farm some more to get plenty $ before unlocking the series, or will the cash for the first car discount be enough to be going on with and I can see where it goes from there?

Wanting to get all the discounts, but not much money at the moment as I have been upgrading lots. Also are there a lot of tiers in the series?

Any advice or screenshots would be welcome from those who have gone before me.

Many thanks!
