Bmw i8 how much does it cost. I go through cars very frequently and i feel tremendously blessed to have owned a lot of great sport vehicles like the honda s2000 subaru wrx sti mitsubishi lancer evolution and prior to the m4 the m235i xdrive. The bmw x3 was the right sized suv sav for my needs. To wow them perhaps the racyspacey new bmw i8 is just the thing. Being fun to drive is not just a bonus for me.
