Nice finds. Let me add a few others that are equally hidden and cool.

If your car has an automatic transmission, you have 2 pedals (one for gas and one for brake), HOWEVER, if you have a manual transmission, you have a 3rd pedal! I think it's to the left of the brake pedal, though I can't be certain.

Speaking of the gas pedal. It turns out that the harder you step on it, the faster the car will go EXCEPT if you are in park, then no matter how hard you press on it the car won't go, it will just make a lot of noise.

The exact same key that you use to open the car can be used to start it.

The radio has AM AND FM stations.

There is a giant panel of glass located right in front of you when you are sitting in the front seats that blocks the wind and rain from hitting your face when you drive. You'll just have to take this one on faith since it's glass and thus after all somewhat invisible to the naked eye.

There is a panel outside on the back right side of the car that hides a secret tube/duct/hole (whatever you want to call it), that whenever you connect a fuel hose to makes the fuel amazingly disappear ALONG with the money in your wallet.

All four tires have sensors that in the event they pick up a nail, are damaged, or hit their minimum thread rating will send a signal to every tire dealer in the country to raise the prices on those tires 25% above what they were just one day ago and declare that inventory is so dangerously low that if you don't immediately buy 4 tires with warranties today, you might be driving home on 4 rotors tomorrow.

The dashboard cluster has a number of lights that incredibly will illuminate only when your bank balance and stock portfolio are at their lowest levels of the year.

When the car is just out of warranty, and only when it is out of warranty, and requires repair service, the BMW Assist service will call the service advisor to quote you $5,000+ in repairs and remind you to go have a free coffee in their lounge while they look for more stuff that needs replacing else the car will implode itself.

While enjoying said free coffee, all new car brochures have miraculously disappeared and sales people have no idea what you are talking about when you ask for one.

Having abandoned getting a new brochure, a visit to the parts counter to ask to look up anything more than a single part yields an expression from the parts guy like you asked him to pass a kidney stone as he desperately seeks to leave in order to get back to viewing internet porn.

Incredible stuff these BWM 5X's
