Are you sure that was to extend the warranty and not the free maintenance plan? I'm pretty sure extending the maintenance plan costs between $1200 and $1400. Extended warranties are closer to $3000-4000 and that's even through reputable third party companies, not directly through BMW.
Then again what are the odds of me keeping it passed 50k miles.

Either the finance guy is clueless and doesn't understand the difference between the two (maintenance vs warranty), or he's trying to sell you a nearly worthless third party warranty which excludes more things than it covers and has such a large co-pay, nobody would use it except for major problems. Did he happen to give you a brochure or plan name? If so, would you please post the details? If there really is a way to double the length of the warranty for that price, nearly every sane 335/535 owner would jump on it without hesitation.

Yep. Just searched the M3 forums. People paying $1400+ for the extended maintenance and over $3k for the extended warranties!! And thats on the low side. Thats crazy.
This is the first BMW that i had where the electronics made me nervous. Theres so much in the M3 in terms of technology that im sure something might go wrong.

lito, like I said over at e90post, congrats!!!
I wish we have gotten the Coral Red interior, but since our 335i is primarily my wife's DD, she had the first pick in the interior color. It's alright though because my S4 will have red interior.

congrats and welcome to bimmerzine! I just ordered the M -TECH front lip. I'm debating on getting the carbon fiber splitters for the front lip.. WHat do you guys think?
Beautiful! IMHO, that's the perfect E92 M-Sport color combo. 
Unfortunately for me, an E92 isn't practical when you have kids and even the E90 just seems too small. So earlier today I ordered a loaded 2010 535i M-Sport; however, it's not scheduled to arrive until mid-October thanks the yearly August production shutdown.
It's going to be a long three months.

Have any of you guys done the Juice BOX 2 or 3 MOD? If so, what do you think about it?

There is a ton of info on Bimmerpost
Basically, I go back and forth every day, one day with my finger in the purchase button and the next with the it's not worth losing my warranty mentality.
Dude, I would have gone with SSTT, or just the regular juice box. Those are really mild tunes. If you truely came into some good money like you said, then I wouldn't think twice about a dinan reflash, or xede ecu reflash (so that the computer is set up right), and a twin turbo upgrade in the near future. Just simply slapping on JB3, is really risky! Enjoy your purchase, but I wouldn't do it.

I believe you are upping the boost levels on the car by sending false signals to the car's ecu. Simply upping the boost, is doing nothing for timing, and you will probably get detonation. Also I've heard that some of our turbos give out at about 100,000miles! I'm sure you will SIgnificantly shorten the life of our two small turbos by turning up the boost as high as JB3 does. To each, his own though! go ahead and buy it GIBSON!
Check E90post.com. Someone F**ked up his engine and turbos on JB3! He even posted pictures. Usually guys don't man up and post stuff on the net when their car gets messed up, all they want to do is show you dyno's and racing vids. As I said, do whatever you want. There is nothing wrong with the product itself, but you need to put some money into your car, if you want it to handle that kind of extreme extra power, and still be reliable as stock.

Looking for more boost, smoother throttle response, and a higher level of engine safety? You own the 'Ultimate Driving Machine,' so why not push out all the 'juice' you can in your N54. With the arrival of BMS's new Juice Box 3 all of this can be had and much more. The JB3 is a completely new hardware platform designed by BMS specifically for tuning the N54 engine. Unlike the Xede or Interceptor that are bought from the manufacturer and relabeled, the JB3 is based on the PIC 18FXXX family of programmable microcontrollers along with the hardware, firmware, and software designed by BMS to cater to the N54. As a result, the JB3 allows for a higher boost level on pump gas, smoother partial throttle performance, and enhanced engine safety at higher boost; All of this in the simplest and more reliable of platform, exactly meeting the needs of you and your N54 without extras to jack up the cost or complicate things. The JB3 will come in two versions, the Plug and Play and the Pin Out version, there will likely be a huge shortage on release for the Plug and Play version, those that opt for the Pin Out ($200.00 Less) version will be more readily available to ship.
^JB3 Unit
Features
The microcontroller programming of the JB3 allows for a whole new level of tuning for the N54.
1 - CPS offset (AKA "timing control"), allows a little more boost on pump gas, which was not capable with the JB2. In addition, boost will be mapped by RPM which is now fed in from the Crank Position Sensor.
2 - AIT (Air intake temperature based boost decay). As temperatures rise due to surrounding conditions and extended loads, the ECU actually raises boost, which is good enough for the factory tune, but with the JB2, BMS has been limiting boost to account for the most extreme conditions. With AIT based boost decay the JB3 will auto-tune itself on the fly for the current conditions. High-temperature (>90 degrees) performance will be similar, but when temperatures are cooler the JB3 be able to increase power considerably. Those of you with intercoolers will really benefit from this processor.
3 - Throttle based boost input. The JB3 will adjust the boost targets as a function of throttle input for smoother partial throttle performance.
4 - Fuel pressure remapping. As a part of the 29.2/v81 compliance package, by remapping the fuel pressure more fuel can be sneaked past the ECU. Since the ECU is measuring fuel consumption now to determine if you have a tune this is a critical benefit for diagnostic invisibility.
5 - "Direct solenoid control". The JBX series relies on vacuum line configurations to trick the ECU into a higher solenoid duty cycle, which actually works well. But the JB3 handles the I/O of the solenoids directly, eliminating the need for any changes to the vacuum lines. BMS has developed a method to adjust the solenoid duty cycles without having to replicate the internal boost control system and without having to add an external power tap or huge resistors.
6 - Multi-position persistent (e.g. stays where you set it) map switch. This allows you to go between stock, 91, 93, and the race gas tune on the fly with the turn of a dial. No more turning the car off first, and no more issues with leaving the race map on 24/7! Wireless options are not planned for now, but there are other options in the works for easy map switching from in the car.
7 - Lean-cruise mode, for those of you looking for maximum fuel economy on your private roads. Ideally selectable via the map switch. BMS is also toying around with the idea of nerfing boost on this map to 2-3 psi, so your 335 feels like a 328. Perfect for saving when you need to and feeding the beast when you have to!
8 - Plug and play harness. The JB3 harness is color keyed and completely plug and play for super easy install. Power and ground come through the harness directly so there are no external taps or grounds, and no extracting of power wires. Just the 4 ECU sub connectors.
BMS also offers a pin out harness for a less expensive alternative. There are 11 pins total so install on the pin out will be for professionals only.
Results/Gains
As far as results go, it will all depend on mapping and boost levels. BMS strongly believes and advises in the use of a boost taper and avoid putting extreme loads on the compressors. The race gas mapping is expected to be similar to JBX race gas mapping, meaning a little over 400rwhp on race gas.
The real benefit of the JB3 will be in the pump gas power, drivability, diagnostic invisibility, and ease of install/removal.

Nice pickup Evil, I've read about tons of people who love the BMS tune. Good luck with ti.

JB3 has adjustable maps. There are risks with any mod, of course. I'll probably end up doing the same thing. I've only had my car a couple months so I'm not in a huge rush to do anything.

Nice buy on the JB3! Its a very popular tune which says a lot in itself.
And yes, I can get the Vorsteiner bootlid.
