All used up: Pre-owned sales rise as consumers seek new-car alternatives

Used-car sales took a leap upward in April, and the trend is expected to continue at least until midyear as pent-up demand for affordable pre-owned vehicles jacks up at least one segment of the car marketplace. Sales of new cars continued an unabated slide toward what analysts say is a 30-year low in the United States, but used-car sales showed strength as buyers unable to finance new cars shifted their sights to less expensive used models.

Arrinera 2013 Arrinera

New Polish car company Arrinera has announced that work on the prototype of the new model – also called the Arrinera confusingly – is complete and it will now be embarking on moving the design to production. The company has claimed that the inspiration for the car's design came from that of the stealth-fighter, although there are obvious features reminiscent of Lamborghini, such as the doors, a Reventon-esque front end, Gallardo-like rear intakes, and vents ahead of the rear wheels similar to those on the Murcielago. Arrinera asserts that the cabin will be adorned in only the finest handcrafted leather and carbon fiber and highlighted with aluminum trim.
