The Cadillac XLR is a luxury roadster that was marketed by Cadillac, assembled in Bowling Green, Kentucky. Intended to be Cadillac's flagship sports car, the XLR was based on the Chevrolet Corvette's Y platform. The XLR featured its own unique styling, interior, and suspension settings, and power-retractable aluminium hardtop, along with the Cadillac Northstar engine. The XLR ended production after the 2009 model year.
The car was based on remaining Chevrolet Corvette C5 assemblies due to GM's transition to the C6. Cadillac introduced the XLR at the 2003 Detroit Motor Show and began production in the 2004 model year — foreshadowed by the Evoq concept vehicle.
The XLR features as standard equipment heated and cooled leather seats, wood interior trim, remote keyless access, 18 inch alloy wheels, side airbags as well as a navigation, audio, and DVD system sharing a 7-inch dashboard screen. The retractable hardtop itself is constructed of aluminum, requires 6'-10½" of vertical clearance during retraction, and is manufactured by a supplier joint venture between Mercedes-Benz and Porsche. 
The XLR was the second roadster offered by Cadillac in recent years. The first was the Cadillac Allanté, produced from 1987 to 1993.
The XLR was nominated for the North American Car of the Year award for 2004.The XLR replaced the Allanté.
The Cadillac XLR was marketed as a luxury roadster, and therefore included many standard luxury and convenience features. Many of the XLR's standard features were optional, and in some cases not even available, on the Chevrolet Corvette (C6). These features included a touchscreen GPS navigation radio with an A/M-F/M radio, CD changer, XM Satellite Radio, full voice control, and a full Bose premium amplified audio system, Bulgari-branded clock,  OnStar, High Intensity Discharge (HID) front headlamps, a power-retractable hardtop roof, perforated luxury leather-trimmed seating surfaces with power-adjustable, heated and ventilated bucket seats with a driver's memory system, luxury carpeted floor mats with embroidered 'XLR' logos, premium aluminum-alloy wheels, and wood interior trim. Bulgari also designed the gauges in the instrument panel for the 2004 XLR.  Whereas the Chevrolet Corvette (C6) was powered by a 6.0L LS2 V8 engine, the XLR featured Cadillac's 4.6L Northstar V8 (which was also supercharged in the XLR-V), and while the C6 Corvette offered a six-speed manual transmission, the XLR featured either a five-speed 5L50 automatic transmission, or a six-speed 6L80 automatic transmission. No manual transmission option was available for the XLR, as it was marketed as a luxury roadster, while the C6 Corvette was marketed as a sports car. There was few optional equipment available on the XLR, aside from premium polished aluminum-alloy wheels, exterior and interior color options, and different interior trim options.
Also notable was the XLR's styling that set it apart from the Chevrolet Corvette (C6). While the C6 Corvette featured only a lower front grille, ovular front headlamps, round tail lamps, and simpler exterior styling, the XLR featured a silver-painted upper "Egg Crate" (XLR) or chrome wire mesh (XLR-V) front grille, angular front High Intensity Discharge (HID) front head lamps, vertical rear tail lamps, and chrome exterior details. Inside, the XLR featured wood interior trim in addition to the C6 Corvette's aluminum trim, and different seats. The C6 Corvette did not offer a hardtop roof, and the XLR did not offer a cloth convertible roof.
The Cadillac XLR-V, was a high-performance (443 HP) version of the XLR. Cadillac gave the public its first glimpse of the supercharged XLR-V in its Super Bowl commercial, which aired February 6, 2005. Super Bowl MVP Deion Branch was also awarded an XLR. The car was formally introduced at the 2005 New York International Auto Show.
The XLR-V used the same supercharged Northstar V8 as the STS-V, though output was down somewhat. For the XLR-V, the engine was certified by the SAE to produce 443 hp (330 kW) and 414 lb·ft (561 N·m). The supercharger and four intercooler cores were built into the intake manifold. A six-speed automatic transmission, larger brakes from the Z51 Corvette, and 19-inch wheels were used.
The XLR-V could accelerate to 60 mph (96 km/h) in 4.6 seconds according to Car and Driver's tests. The magazine also timed it at 11.3 seconds to 100 mph (161 km/h) and recorded a 13.0 second quarter mile at 110 mph (177 km/h). Its top speed was electronically limited to 155 mph (249 km/h). 
The XLR-V went on sale in the United States in early 2006 with a base price of $110,000. Pricing for the 2008 model started at $111,300; making it at the time one of General Motors' most expensive vehicles.
For model year 2009, the XLR added a new front fascia, new rear fascia, and chrome side fender vents. Inside, Alcantara - a suede-like microfiber material - was added for the headliner. The interior added new instrument cluster trim rings with revised graphics, (removal of the Bulgari logo) and new wood dashboard trims. Production of the XLR ended in the spring of 2009, with the final example completed on March 31.
MSRP - $86,000. 
Starting with the National Corvette Homecoming 30th anniversary in 2011, the "cousin" of the Corvette the Cadillac XLR has been included in the celebration. The XLR and XLR-V were all built at the Bowling Green Assembly Plant and are welcomed at the annual homecoming at the NCH in Bowling Green, Kentucky. This includes special displays at the car shows, XLR seminars, XLR VIP appearances and inclusion in the vehicle parade and other activities.
XLR Owners had their own "10 year Anniversary Homecoming" at the Bowling Green Plant on 28 September 2013. Owners from across the country and Canada were in attendance for plant tours of the C7 production line, car cruises, and a Car show sponsored by the Bowling Green Assembly Corvette Club. XLR Owners and Corvette Owners have shared several national events/gatherings. In addition to the National Corvette Homecoming, the visitors will find XLRs in attendance at Corvette Funfest, Bloomington Gold, and Carmel Artomobilia.
Many owners also participate in an annual XLR "Rendezvous":
