pure competition as in "race to the bottom": cars are leased for the cheapest price, components are cheapest and the manufacturers' warranty expires with the first lease. Dealer who owns the vehicle re-leases the vehicle with a third party warranty if it's in good shape. Tuner, i.e. individualized cars are soon to be extinct, hence the BBS bankruptcy. Finding pre-bankruptcy parts from any original source will become a collectors' and builders' dream (think art fakes and insurance fraud) Metal composition testing, tracking down the original sources of ores (think antique authenticators), x-ray analysis, whatever.
There's even a gray market for saw mill cutting blades. A local saw mill operator on my rural road was swindled.
