The demise of the American Le Mans Series at the end of 2013 ushered in not only a new series (the Tudor United SportsCar Championship), it also ushered in a new era for the storied Porsche 911. The Stuttgart manufacturer debuted the 991 GT3 RSR chassis at this year’s Rolex 24 Hours of Daytona. Meanwhile, the previous-model 997 GT3 RSR was relegated to, well, whoever has the money for one. Enter ZSA Motorsport, who are selling on eBay what they claim is the very last Porsche 997 RSR built . Follow the jump for more.

The chassis in question (WP0ZZZ99ZCS799912, if you’re curious) debuted for Flying Lizard Motorsports at the February 2012 ALMS test at Sebring International Raceway. Porsche factory drivers Patrick Long and Jörg Bergmeister campaigned the beast in 2012. It was a challenging year with the 997 looking a bit long in the tooth, taking home only one win at Mazda Raceway Laguna Seca and finishing a disappointing fourth in the GT championship.

Last season, CORE Autosport took the reins of the car. In retrospect, this appears related to the team also taking charge of the Porsche 991 factory team for this season. Patrick Long stayed on and co-drove with Tom Kimber-Smith, Colin Braun, and his 2014 partner Michael Christensen. While the car was nominally competitive with two podiums, the car’s 2013 purpose seemed more to acclimate the CORE crew—who had and still do run a high-quality Prototype Challenge car—to Porsches with a factory driver pushing the development.

The 2012 updates to the 997 widened the rear track substantially, giving it an aggressive look that this writer finds rather appealing. The same writer, however, is not entirely sure it’s the last 997 GT3 RSR ever built, although Porsche did stop building them that year so it’s possible. It was certainly the last ALMS 997 GT3 RSR along with the Falken Tires car, which was written off in last year’s disastrous Baltimore Grand Prix green flag pileup. 

Bidding starts at a hefty $375,000, although the sellers claim (believably) the car has more than $1 million in it. What does that price tag get you? It includes the car built to RSR specs with the 2013 4.0-liter flat six, a custom interior, a substantial spares package, and two years of development work from factory Porsche drivers at the hands of professional engineers (Good luck getting their setup notes, though).

Few of our readers are probably in a position to drop multiple hundreds of thousands of dollars on a trackday or historics toy, but there is some serious collector value in this car. You should be surprised if this 997 GT3 RSR lasts a week on the auction block.
