first cars, MBTA forced Boeing to make 70 to 80 modifications on each car. Boeing ended up paying in damages to Boston. The purchase price for each car was . The federal government offered to provide 80% of the funds for design and production of the USSLRV in exchange for a commitment to keep the cars in service for at least 25 years, but the cars, as-delivered, were prone to jammed doors, defective brakes and motors, leaky roofs, mechanical breakdowns, and were involved in several accidents. Muni Metro added 30 more cars to the fleet; these 30 had been rejected by MBTA after suffering numerous breakdowns. In 1982, the Boeing cars averaged only between breakdowns; by 1988 this had improved to between breakdowns. In 1998, Rudy Nothenberg, president of the Public Transportation Commission, said the Boeing cars were "impossible to maintain and [...] have many, many design flaws;" that same year, Muni was only able to supply 66–72 working cars for rush-hour service instead of the required 99 cars, resulting in system delays. Despite the shortcomings of the USSLRV design, these cars constituted the entire light rail fleet until 1996, when new Breda-manufactured cars were put into service, replacing Boeing cars as they were accepted for service. By 1998, the 136-car Muni Metro fleet consisted of 57 Boeing Vertol cars and 79 Breda cars. Two Boeing cars were preserved for potential donation to the San Francisco Railway Museum, but have since been scrapped; five were sold to the Greater Manchester Passenger Transport Authority for the modest price of to each; one was acquired by the Oregon Electric Railway Historical Society in 2001, but the Society declined to take any more Boeing cars after experiencing several breakdowns. Boeing car no. 1258 has been on exhibit at the Western Railway Museum near Suisun City since its acquisition in 2002. LRV 2 & LRV 3: Breda (1996–present) The first of four prototypes of the new Breda cars was delivered in January 1995. After delivery of additional cars and training of operators, the cars began to enter service on December 10, 1996. They were the most expensive street railway vehicles built to-date, at a cost of each, and they were assembled at Pier 80. After suffering initial breakdowns and despite facing complaints of noise and vibrations, the Bredas gradually replaced the Boeings, with the last Boeing car being retired in 2002.
