The xA is only sold as a 5 door hatchback. The only engine option is a somewhat weak I4 engine that makes about 105 horsepower. It is paired with a 4 speed automatic or 5 speed manual transmission.
This car is seen by many as an upscale version of the Toyota Echo in hatchback form. It has better performance parts like a stiffer suspension and bigger brakes. It also has power windows and locks and Pioneer MP3 stereo standard, something not found on the barebones Echo.
The Release Series was a limited edition version of the Scion xA. There were 3 types of these cars, the RS 1.0 was sold with Absolutely Red paint, the RS 2.0 was sold with Spectra Blue, while the RS 3.0 was sold with Stingray Metallic.
These cars were replaced in 2007 by the Scion xD. The xA might still be sold new in parts of the Middle East. It was the poorest seller of the Scion models.
I've noticed some of the Scion xA's are already showing up on the used car market. You can find accurate pricing by looking on eBay and Craigslist listings. I would avoid Kelley Blue Book, as their prices rarely reflect real-world variables like location and other specific condition factors.
