I think its worth it for the M6 car if you want gears. The auto can run the 4.09:1 without a tune, but not the M6. On my S550 4.09 gears were a match made in heaven for the MT82D4.
Part of the reason I didn't move forward with the S650 is the terrible leasing and price but also the lack of tuning, I went ahead with my G87 M2 which I do love. I have to admit if this was out with the current pricing (lease) of the S650 it definitely could have changed my mind.
I think its great news. What shocked me is worth ported heads and intake and all the other mods this car only made 434rwhp. The tune is just putting it all together.
For Veterans you can't have been off of active duty more than 2 yrs. Which is a bummer. I bought my M2 and BMW didn't care when I got out as long as you were a Veteran.
What is sad is they used to cover that. In 2020 they changed that. I remember at 38k miles on my 04 E46M3 I got new rotors. Now you have to pay for that package. However, my dealer also offers free loaner cars. In fact I had an 850i as a loaner for the day while my 1200 mile service was done.
To be frank the 1st 4 yrs of ownership BMW does all the maintenacne. After that just use an independent service. My last M car, a 2013 E92 M3 I had for 8 yrs and the car never saw the dealer for work on the car other than maintenance.
If I go single I am going with the Miltek as its 4" in diameter. I don't like the fact that most single midpipes are only 3.5". A single 3.5" doesn't flow as well as the OEM 2 2.75" piping.
I had an E92 M3 for 8 yrs. not once did the car go in the shop for anything. That car was bulletproof as well. I sold the car with 60k miles the guy went and had the rod bearings done and they were fine. I can't say the same for my 2020 S550, 2 oil pans, 2 bad 02 sensors and multiple recalls.
