Any issues to be wary of...
 

Just curious to see if there are any issues with the newest generation of the 6 to be aware of?

i have a 2015 mazda 6 GS with the luxury package. its basically a GT minus the 19 inch rims and bose system. so far i cannot find a single complaint about it, i got about 1500km on it right now. the computer screen is a bit small and the resolution is not high, but the system itself if great. the basic sound system is better then expected but the bass sounds a little weird compared to the system in my friends 07 mazda 6 with the bose system. i hope this helps. if you are considering purchasing the new mazdas then go for it! you will not regret your purchase. they have put a ton of engineering into this car and i am enjoying it so far.
