Time included the DeLorean in its list of the 50 worst cars of all time. In his book Naff Motors: 101 Automotive Lemons, Tony Davis described the build quality as "woeful". Top Gear writer Richard Porter included it in his book Crap Cars, calling it "dismal". Performance DMC's comparison literature noted that the DeLorean could achieve in 8.8 seconds when equipped with a manual transmission, but other sources indicate an acceleration time of 9.5 seconds. When equipped with a manual transmission, the DeLorean accelerated from in 10.5 seconds as tested by Road & Track magazine. The car was described as "not quick for a sports/GT car in this price category" by Road & Track. Quality problems DeLoreans, early-production models in particular, suffered from poor build quality as well as mechanical issues. Early-production cars needed as much as 200 hours of work at DMC Quality Assurance Centers prior to being shipped to dealerships for delivery. DMC eventually sent 30 factory workers to the quality centers in the US to learn about the problems and how to fix them. Quality did improve over time, and by 1982 many of the quality issues had been resolved. A total of four recalls were issued by the factory to correct problems such as a sticking throttle, front-suspension issues and an inertia switch. Other quality issues included other problems surrounding the front suspension, clutch pedal adjustment (or lack thereof), brake rotors, instruments, in particular the speedometer, power door locks and weak alternators. Many early DeLoreans were delivered poorly aligned, with the toe-in incorrectly set, leading to premature tire wear. In addition, many dealers were reluctant to perform warranty work on DeLoreans, since DMC owed them money for past warranty claims. Some dealerships were not able to perform repair work properly, as DMC never issued a proper service manual. The lack of quality service at dealerships was a point of frustration for many DeLorean owners at the time, particularly those who paid over sticker price to purchase one of the first cars. Pricing and options Base price Upon release in 1981, a DeLorean had a base MSRP of $25,000, or . MSRP increased in 1982, to $29,825, , and again in 1983, to $34,000, .
