Thinking of getting a car.

Stuck between the G8 or Infiniti M45

Both have similar power, performance and interior space.

The M45 has nicer interior with GPS Nav but you pay $10-15k for it too.

Only thing that worries me on the G8 is parts availability later on.
GM has said it is not going to continue the G8 as the Caprice.

Would you guys be worried about finding parts for a car that was only
made for 2 years, by a company that has been Nationalized and who
knows what asinine road they will take from now on ?
