I love our Indigo edition.. I liked it more because of the brown interior... was tired of black and tan in our other vehicles..
Basically the Indigo edition is a base GT trim in deep chroma blue with some of the GT1 goodies (HK Sound system, larger 8 inch infotainment with Nav, sunroof, ) and the mechanical bits of the GTS D-AWD special edition (Suede-like headliner, D-AWD, rear mechanical LSD (Limited Slip Differential), Revised logic for transmission/torquevectoring/and stability control, and Drift mode). The only things i wish we had was the ventilated seats and the rain sensing wipers..
