Count me among those who chose to go with the MY LR instead of the MYP which I originally had on order. I am in the process of charging the car and I just purchased the AB a few minutes ago. I'll see if it was the right choice for me. I couldn't stand the 21" Ubers on the MYP, I am not a fan of the Inductions either as both wheels are way too heavy.
The performance suspension is MEH in my book and if I bought the MYP, I would have had to change it pretty quickly as my wife hated the ride quality. So the way I see it, I saved 8k and only gave up 1/2 second to 60 mph. Since my days are not filled with 0-60 sprints everywhere, I am fine with that. The performance brakes will have no impact on the way I use the car. The wider rotors are the only real upgrade there. I am not overheating my stock brakes and typically drive where regen is my friend. The lack of the track mode was a major oversight.
I can make my MY LR look like the MYP for about $400 bucks if I want to impress people and if that matter to me. While 1/2 second is significant, it will almost never matter to how I drive the car. Maybe good for bragging rights if so inclined but the M3P will run away and hide from the MYP if that is your thing and the M3 LR with AB will probably run heads up. So if I was worried about the 1/2 second, I'd go with the faster, better handling platform rather than putting lipstick on a ...
Not saying the MY is a pig, but compared to the M3, it feels a lot less athletic. So the MY LR seemed more in line with the mission of the MY. Not to say I wasn't interested in the MYP. Like I said, it was the one I had on order first. For me the only real plus of the MYP was the greater thrust. If they had the stealth version still available, or the it came with the track mode like the M3P, then I would have likely stayed with the MYP.
I think this who discussion breaks down along two camps.
MY LR AB - I am >< this close in acceleration to the MYP for only a 2k upgrade. Look at all the money I saved. I am definitely on the correct side of the diminishing returns curve. What is a half second difference anyway? Is it really worth 8k more? I do like that spoiler though. Maybe I can find one on Amzn of Fleabay. I thought I saw some brake caliper covers. We have the same brakes anyway, well the calipers are.
MYP - Yes, you saved 8k over the MYP but you don't get these really cool, but super heavy 21" staggered wheels (that you can't rotate, and a nice little hit on the range too), the nifty spoiler, the cool pedals, the red calipers that mean it MUST be a performance car. Did I mention, it is over 1.3 seconds quicker 0-60 than the MY LR. Well, maybe not totally 1.3 as the time for the MYP doesn't factor in rollout, but at least 1 second quicker, and a whole 1/2 second quicker than the MY LR w/AB. Did I mention it has performance suspension? Hopefully you don't value ride comfort as it rides rock hard like my abs! I can go 155 mph vs your 135. I'll be exercising that speed advantage every day, you betcha. Ignore the Car and Driver road test where the MY LR (without AB) beat the MYP to 130 mph by more than 1/2 second, everyone knows the MYP is faster than the MY LR at any speed.
Before anyone gets wound, up the previous 2 paragraphs are meant in jest. It seems sort of boils down to those 2 approaches. Everyone thinks their position is right. I think they are. I know if I had bought the MYP, my wife would have been pissed off anytime I floored it with her in the car. She hit me when I punched in the M3P. She would have complained about the ride quality as well. So I would have had to swap out wheels and tires which immediately would drive the cost delta to a lot more than 8k. Yes, I would have gotten a better car but even more $$$ sunk into it. TBH, the stock MY LR isn't quick enough. If there hadn't been an AB option, I probably would have figured a way to get my wife on board with the MYP. If I was going to frequently track the car, then the MYP would be more fun, but there are better horses to run at the track.
There are any number of ways to rationalize your choice. If you are happy with it, then great. I am very thankful that we do have choices. Without the AB option, I probably would have been unhappy with the MY LR long term. Who knows I still may want more than it will provide but I hope the AB option will sort of be the Goldilocks version. I'll know in about 2 hours or so when I can take it out after another storm passes us. Enjoy whatever MY you are driving. It is a really fun car in any trim.
