The US's leading satellite radio service. XM will offers 121 channels of digital satellite radio as of March 1, 2004.

Satellite Radio service has been providing digital audio streamed to XM ready receivers since 2001. Currently has 6,000,000 plus subscribers who receive more than 160 channels. Premier content includes personalities such as Snoop Dog, Bob Dylan, and Bob Edwards, while also providing excellent shows such as Artist Confidential and Opie and Anthony.

Okay that was a legitamate definition. As a bonus, I will now define Sirius satellite radio:

Sirius Satellite Radio is a dumbass waste of low orbit satellite traffic that will probably go under as soon as they open up their check book to pay HOOHOO-Has-Been-Stern his first 100,000,000.00 check. Sirius offers 120 channels of digital music, unmatched NFL coverage, and a vile of aids infected blood to inject into your veins once you find out how shitty and and pathetic its audio content really is. Listen with joy and unmatched euphoria as you enjoy channels that may or may not play music that fits within the parameter of the Channel genre. Watch with awe as your brand new $300.00 S-50 Portable unit refuses to turn on because of the shoddy craftsmenship of Sirius's thirdrate manufacturer "Directed Electronics". Excercise those jaw muscles, for they will surely drop once you find out that your 300 dollar portable unit DOES NOT receive live satellite feed, but rather "Pre Recorded" audio that you have to load via the home antenna kit. And for you Howard Stern fans! You'll be entertained for hours on end as Howard bitches about how the government is still trying to censor him. Watch as he cleverly invents new reasons and explanations as to why he is incapable of doing a funny, intelligent, entertaining program. And watch as he explains to his fans how he is only going to do a show for 4 days a week and only 9 months a year. But dont fret! There's always Bubba the Love sponge! Whats that you say? Howard hates Bubba? Not anymore! Howard loves the sponge! Forget all those nasty comments he made about him in the past. Everything is dandy for these two shock jocks who never go back on their word and always stick to their guns.

Abbreviation for eXtreme Makeout Session.

A makeout session ranging from 1st to 3rd base depending on the situation, location, or mood.

Usually planned ahead with no emotional attachment or strings attached.

The XM is a large car built by French manufacturer PSA Peugeot Citroen between 1989 and 2000.
The XM is regarded as an excellent car by enthusiasts, who relish it's rock bottom second hand values, and enjoy equipment and trim levels similar, or even superior to that of other luxury cars such as BMWs and Mercedes.
Universally and somewhat undeservedly feared by the non-initiated public, and Citroen dealers alike. Not a car for the faint hearted, or those afraid to get their hands dirty. That said, most the stories about the car's legendary complexity are easily dispelled with a little research / advice from fellow owners. It's actually not that hard to understand (nor that unreliable) when you see how it's supposed to work.
In spite of this, mechanics at service departments cower in fear when an XM pulls up outside. The Citroen dealer network's knowledge of the car in some markets, particularly the UK and Ireland, is utterly abysmal.
Perhaps this is due in part to the low sales of XM's in these markets, meaning that they have little / no experience of the car. Indeed, some of the younger service technicians profess to never having seen one.
As a result of this, rare is the XM enthusiast who would trust a main dealer to go anywhere near his beloved car. Most owners tend to be self supporting, though many reliable independent garages who specialise in Citroens do exist, and are widely utilised by those in the know.
Numerous excellent internet resources exist for the discussion of XM's, including the XM-L list on Yahoo Groups. www.citroenet.org.uk is another excellent fountain of knowledge on XMs, and Citroen's in general.

Looks wise, you could be forgiven for believing the XM to be the result of crossing a whale with a Delorean. It's pointed, angular, almost fierce looking, aerodynamic front gives way to a large, wide rear. It is also reminiscent of a 'cheese wedge' shape, which it is sometimes referred to as. Time has been kind to the XM's features, and it looks futuristic even today, some 17 years after it's initial debut. Indeed, it's striking looks resemble nothing else on the road, and it still draws stares from bewildered passers-by.
A facelift 'Series 2' version was released in 94-95, in which the front grille was changed to match the 'corporate nose' already worn by the smaller, but less distinctive Xantia. There were many other changes to interiors, engines, and specifications, but many XM enthusiasts prefer the original Series 1 front grille, and the highly unusual single spoke steering wheel, which offers an unobstructed view of the highly packed instrument panel.

The XM is often referred to as 'The Enterprise, --Millennium Falcon--', and other sci-fi euphemisms, due to the fact that it has more gadgets, buttons, and lights than you would find on the console of a starship.
Performance wise, it is an intergalactic motorway mile muncher. It is content to sit at 90mph on the motorway all day, without so much as a whimper, it's passengers in perfect comfort the whole time. Indeed, due to the superior hydraulic suspension system, and excellent handling, many XM drivers report feeling alert and refreshed, even after a particularly long journey.
The car's dynamically adapting Hydractive system, fitted to all UK standard models, allows for highly spirited driving on twisty, bumpy roads, without diminishing passenger comfort or safety. Indeed, drivers of smaller, supposedly more nimble cars are often left gobsmacked as it blasts into the distance, after they make the mistake of goading one into a race on a roundabout or snaking country road. The look of bewilderment upon their faces is indicative of the fact that they clearly did not expect such agility from this old, heavy, wallowing French barge. In the words of an infamous XM owner "The XM moves like an 18 stone ballet dancer".

The estate models are renowned for their utterly cavernous boot space. Indeed, they have been known to swallow washing machines and tumble driers whole, in a TARDIS like fashion, whilst still leaving space for the rest of the kitchen contents.

The XM is the successor to the legendary Citroen CX, and precedes the new Citroen C6.
The XM shared a platform with PSA's other car, the Peugeot 605, which ironically, was also one of it's main competitors. Other adversaries include the Renault Safrane in the domestic French market, and the Ford Granada and Vauxhall/Opel Senator internationally.

The XM isn't perfect, and can exhibit a plethora of strange, and often bewildering faults. That said, the majority of these are minor, though their relatively high frequency may go part way to explaining the car's reputation of being unreliable. These minor issues are a common source of frustration and amusement among XM owners. Many problems are well known and documented, and indeed are not to dissimilar to problems that most cars of this age and specification experience.
One amusing side to this is the use of 'XM Radio'. This is not to be confused with the Sattelite based radio service of the same name. Instead, it involves tuning the car's radio to a particular FM frequency, and then driving around listening for the whines which signify the operation of the electrovalves in the hydraulic system. This is a commonly used, and useful tactic to troubleshoot problems with the Hydractive suspension system.

The XM is reportedly on the edge of being afforded 'classic' car status. It is already somewhat of a cult-mobile, something which is set to intensify as numbers diminish and the cars become rarer still.

A truly great car, technologically light-years ahead of it's time, underappreciated, misconstrued, and feared.
Brilliant !

Satellite radio with a much broader range of music and content than standard FM radio. With Sirius XM, you are not limited to hearing the same song played every 20 minutes as with FM radio. With over 130 different stations, all with different genres of music, the selection available with Sirius XM is well worth the money for those spending a lot of time driving

The inability to listen to more than 20 seconds of a song on an XM channel without flipping through all the other channels to make sure there is nothing better playing somewhere else.

Satellite radio service that is superior to all others.
