GoodCarBadCar.net has finally decided to include the Infiniti G37 Coupe and Convertible in the U.S. rankings of sports cars, roadsters, GTs, and generally sporty cars. BMW still isn’t breaking down 3-Series sales by bodystyle, and Toyota only provides Lexus ISC and ISF numbers in Canada. Nevertheless, the Infiniti G’s sales figures are interesting for a number of reasons.

First, the G37 two-doors are proving more popular than the Nissan 370Z. Possession of a rear seat appears to count for something. Second, there’s the G37 vs. Audi A5 race, one which the Audi’s winning, but not running away with. Finally, the non-sedan G37 is suffering from drastic year-over-year declines. The G25 and G37 sedans were down just 8.3% in March and just 3.4% in the first quarter. 

Of course, the truly popular two-doors are American muscle cars. Chevy Camaro sales were up nearly 4% in March to 9299, 246 more than the Ford Mustang’s total. At this point last year, the Camaro’s lead over the Mustang was a slim 407 units – its up by 1791 this year. By the end of 2011, the Camaro ended up beating the Mustang by 17,811 sales.

March 2012 finished with a German roadster sales race victory at Mercedes-Benz. SLK sales weren’t far from tripling in March, and are indeed double what they were at this point last year. BMW’s Z4 was up 2% to 261 sales. The soon-to-be-replaced Porsche Boxster was 203 sales behind the Audi TT in March.

There are detailed sales figures for these cars and numerous other two-doors and clearly sporting four-doors after the jump. You’ll notice astonishingly strong BMW 6-Series volume. The big BMW coupe and cabrio combined for 3.2% of all BMW sales. For context, Mercedes-Benz’s SLS AMG, SL-Class, and CL-Class accounted for just 1.1% of all Mercedes-Benz USA volume last month. The Automotive News Data Center estimates March 2012 sales for Aston Martin, Ferrari, Lamborghini, and Lotus to have been 68, 145, 29, and 20 units, respectively. March sales for the two British brands in their home market were 207 (Aston) and 10 (Lotus).

Clearly GoodCarBadCar is not suggesting that the cars in the two tables above are all direct competitors. Establishing categories among cars as unique as even the Audi TT and Porsche Boxster has never pleased a single reader, so cars have been lumped together so you can simply see how buyers looking for sports cars, roadsters, hot hatches, convertibles, GTs, and wanna-be sports cars spend their money. Greater categorization of cars would only lead to problems that automakers create by not isolating model-specific sales figures: we don’t know how many M3s BMW has sold or how many Civics are Si models, for example. The numbers we do have are listed above.
