Some 2012's had faulty voltage regulators which were replaced under a recall campaign.

I have ridden a 107, not a bad motor performance wise, but my 103 stage 4 IMHO is a better motor.
You can perk up a 103 for short money, a lot less than what a 107 or 114 bike is going to cost you to buy.
Plus the 14 and newer bikes are HEAVILY computer dependent, the 103's can be worked on by anyone, a lot of Indys are not dropping the $$ for the software to work on the M8's or Rushmore models.

Have TC 103 in my 012 Ultra,no problems. I'm sure the new M8 has a little more snot,but its not worth the extra money in my opinion. Reading all the issues with sumping, trannys,oil migration , I don't think they have any of these issuse resolved, I will keep my 103, don't need the aggravation just to say I have a new Harley.

nearly 50k on my 2012 103 Ultra. Did have the volt reg replaced under warranty, but at that its a $100 part and wouldn't have been too bad to fix in the garage. the VIN will tell you if it was in the failure range.
Else has run great coast to coast. I'd buy another before buying any M8. Good bike.

I have a 2012 Ultra that was 103 stock. Ive owned the bike from new. No problems with the motor or trans.
In comparison to a stock 107 m8, the m8 definitely has more torque and power.
Last winter I installed a Zippers 107 sport kit in my bike. Much improvement. I have no problem keeping up with an m8 now.
