Another solutions 4 limited version on PS+ :
(from PST.org)> Single Event > Time Trial > India > Munnar 01 (forward) with "Pagani Zonda R"
( auto unlock when join some club lvl 15 and above too)
> Single Event > Time Trial > India > Munnar 01 (forward) with ''RUF CTR3 Clubsport'' (unlock at lvl 15)
BUT the way I found 4 myself is > Time Trial > India > ... with "Pagani Zonda R" .... and POPup immediately after 1st try !
