Demo or not. That's a fantastic deal for am 18 440 GC. If you pass on it, please let me in on the dealer and I'll buy it. I don't need it, but I can put it on Turo.

Executive Demos aren't beaters people use on test drives or courtesy cars for oil changes. They're more like company cars that someone would get into deep shit if they mess up. Or they're the cars that the sales people lease out for a few months and have to return. They're treated better than most CPOs

That is so incorrect. You have to beat on a car endlessly for well over that mileage period for anything to go wrong. A new car has all new fluids and parts (obviously) and almost impossible to cause damage.

I’ve seen a executive car with 5k miles look like it had 50k. They definitely do get beat on.

To give some context I’ve had 3yr36k mile leases that I beat in the entire period and nothing ever goes wrong, they’re just too new. And I usually hit 40k+ during my lease term

According to the CPO checklist, there was vibration when braking at highway speed.

According to the invoice from service dept, they resurfaced rotors, replaced pads, replaced sensors front/rear

[Wgosma]

The uneven buildup of pad residue on rotor surfaces is not that unusual a situation., it's a common cause of brake vibration/shudder. The fact that it was noted excessive amount of rust may indicate the car frequently sat idle- was not driven often/regularly and/or lived in a humid or salty environment- I would think that if car lived in Gulf coast this is not surprising to see occur.

do it!

I leased an executive demo and have had zero issues. 12K miles now.

That's due to abuse, someone overheating the brakes and the rotors warped. At 7k miles it's not due to "residue build up"

Just sarcasm quit being overly sensitive, i think OP is getting a good deal and want him to get the car (if he likes it obviously) but i'm just pointing out facts

Warped brake rotors on a street driven car are a pretty rare occurrence. Much more common is uneven buildup of pad material deposited on rotor surfaces, and one does not need to abuse the brakes to have this occur.

and brakes being abused on a long term rental is a much more common and realistic scenario. How many people out there have "excessive pad build up" on a 7k mile vehicle? I've never heard of it, I've never had it in the 20 cars I've owned. Warping is a lot easier than you think, it's not a "track only" thing, especially to cause "VERY BAD vibration".. ok

[Wgosma]

stats show that 4% of cars exhibit significant signs of uneven deposits on rotors, that's 1 in every 25 cars.
Buy a few more cars then report back😉

stats show a dealer isn't going to write "warped due to abuse" for a potential customer to see 😉

I'v owned quite a few more cars than 20, and even more motorcycles, and I can tell you from MY experience that pad build up can occur. This is my 6th BMW.

First thing a tech will do when someone complains about vibration on the pedal or wheel is to measure rotor run out. Based on that, he can pretty much determine asap whether the rotor is warped or there is some build up. The tech will only report what he finds--he is not going to sugarcoat his findings. He has absolutely no reason to lie--his career is at stake.

That said, i've had rotors that I swear were warped, and after a good bead blast with new pads, they are as smooth as new.

I do not know the specifics of this car, but I would have no reason to doubt the tech.

Do you know how much braking force and repetitive high speed stops it takes to transfer a significant amount of pad material. I'm sure you know what bedding is. For it to cause "very bad vibration" this car was not experiencing normal braking habits, sorry, i wouldn't buy it.

wouldn't buy the story* not the car, i'm sure the car is fine

Well, we can agree to disagree. I can only speak from my personal experience--not regurgitated internet research, but i'm sure you are also speaking from your own personal experience. cheers.

Went back to the dealer today with my mechanic buddy. He saw a few things I missed. Nothing major. Just some curb rash and a tiny paint chip. Car brakes fine at highway speed with hard braking or otherwise.

Offered the dealer $36000 and scratch Phantom Footprints ($295) and Permaplate ($499). Sales Mgr said thanks but no thanks

sorry that I haven't driven more, just giving my experience. Unlike you, who is just wiping his asshole on everything.


you seem bitter like you've been burned. sorry pal! Grow up kid.

And why are you so bitter off one comment?

12K miles isn't an "experience" your car is new bud, that's all im saying.

I'm pretty sure it's not one comment, but rather how you come across as a whole on this forum.

I've been around enough car enthusiasts forums to know we all have different personalities and have different ways of communicating--and that is fine. I think this place would be better if before we post think if we're being antagonistic, or being genuinely helpful.

That said, we all share the enthusiasm for the same car -- I hope, so we should all be more helpful towards one another.

I hope you don't take it as a dig, I genuinely do think you have some great contribution here!
