Picked up this ‘10 sedan last October, was recommended to join here by a member of CTS-Mafia on FB. I live about 40 mins south of Boston.

Wanted a stick shift V2 sedan 7 years ago but couldn’t swing one so I bought a ‘15 Regal GS with a manual. Both of them being silver wasn’t planned at all and neither was my first color choice for either car. Other than the colors, it's basically what I wanted with Recaros and UltraView. The car just clicked 145K miles, obviously a bit on the higher side but it doesn't bother me because I'm not afraid to drive the car anywhere.

Still have the Buick and few other cars. The black car is a heads/cam/intake Z28 with a 4L80 swap and a ‘97 SS 30th Anniversary. I don’t have pictures of the SS with the V that’s why it’s not posted. The V is going to be the summer daily. Don’t want to get to crazy with it but definitely want to add some power and sound in the future. I added a warranty for the car when I bought it and they ended up covering a brand new GM diff due to the notorious whine I've been reading about. It definitely silenced a majority of the noise but not completely.

Very nice with the right amount of doors. Drive it like you stole it! I’m just south of you in Providence R.I.

Was having some dejavu, as I thought I saw this post already... then I read the FB Group part and figured it out, haha. Congrats and welcome to V world! Awesome trio you have there. Didn't know the GS came in a manual in the States. Seems like that'd be a fun combo for a daily as well, plus not too bad on fuel.

Welcome to the VZone.
Change your diff oil every 10 to 20K and enjoy a whine free life. If you see metal keep changing every 1K until no more metal...then move to longer interval. Loud pedal + Supercharger whine NEVER GETS OLD!

Curious on the interval and what fluid you use to change? I've never changed rear end fluid in my car since I've owned it and really only once or twice ever on any vehicle I've owned, and that was only because I was swapping diffs for a posi. unit. I've had a couple GM trucks with well over 200k miles without any diff. service, but of course those never saw a ton of power and abuse like the V does. My 8.8's in a few vehicles saw quite a bit more abuse and power and still never cared much for fluid changes, still going strong, no whining or anything funny. What is with GM and these Diffs!? LOL. Before I got my V, the dealer installed a new diff., however, claimed it was only for pinion shaft seal.

But anyways for fluid, what do you normally use? And any additives/friction modifiers?
Nice! Looks clean for high miles.

How much did you pay for it? Im curious what the market for M6 V2s are nowadays, there are like none for sale.
I'm currently waiting to get mine. Black Diamond sedan M6. You picked all the right things except the color. Just kidding. Enjoy every (s)mile. What do you plan on doing first?

Yeah, I try not to abuse it but it doesn't make sense to buy a V and drive it like a base 3.6 car haha.


Not far from either, I'm right in Fall River!

Yessir! From 2012-2015. The GS was manual only when introduced in the States at first and then they rolled out the automatic versions. Of course, the take rate of the manual decreased year after year and was dropped after 2015. I absolutely love the GS which is why I held on to it even though I bought the V. The 2.0T lacks the straight line punch you'd expect given the cars fairly aggressive looks but for a heavy-ish FWD sedan, it handles damn good. Not sure if I'd own one if it was automatic.

Thank you! Good to know. I work at a Cadillac dealer so the fluid change is the first thing I did and there was metal in it. I've put about 1,800 miles on it since the new diff so I'll probably have the fluid changed this week now just to check on it.

Just under $30K with a warranty included. That warranty company then covered a brand new GM diff to the tune of $4,800 4 months after I bought it.

I definitely paid the manual tax but there were really no comparable cars in the market and this one in particular presented itself well. It only had 2 owners, the first I believe was a GM employee and then the second owner bought it in 2011 with 1,800 miles as CPO. He kept it until mid-2022 when he traded it into a Chevrolet dealer.

A 110K mile M6 2009 sedan on BaT just sold for $33K or something like that so that didn't make me feel like I really overpaid.

Trust me, Silver is never my first choice but you have to compromise sometimes lol. It had the Recaros and the UltraView and being Silver, it matched my GS.

If I had the choice, Opulent Blue is what I would have went after.

Nice Caddy! Too bad about the Camaro. :)
Thanks.

Different strokes for different folks. I love my plastic fourth gens. I've had 3 and there will probably be more to come.

Get the GM diff fluid with the friction modifier included.

Welcome from another new Englander. I occasionally travel down to the cape and was at the e-karting place superchargd I believe near you a few weeks ago. So fun.

Good call on the warranty, now now!
