Not one, not two, but 57 high-quality Porsches will go under the hammer at Silverstone Auctions’ Porsche-only event on Sunday 25 October, and these are just a few low-mileage, lightweight examples.

Not so long ago, we actually featured a fascinating slant-nose 930 Turbo SE destined to hit this auction block, but these 6 mouth-watering examples are in a league of their one, being some of the most desirable, thoroughbred RS 911 Rennsport variants ever created by the German car manufacturer.

One of the automobiles is the very first RS model road car of its kind; an “early 500” 1973 2.7 Carrera RS Touring, which was created from the necessity to take the 911 racing philosophy – reduce weight, add power – to the next level. The car benefits from a recent restoration, looks stellar and it’s estimated to fetch between £375,000 and £425,000. That’s $575,953 – $652,693, but what did you expect from an original 901 RS which comes complete with its original tool set and sales brochures from the era. The car is in an amazingly, original good condition.

Of course, no 911 Rennsport collection would be complete without a 964 Carrera RS – the next iteration of the RS name. The example available for purchase is a factory-fresh 1991 3.6-litre model with only 21,500 miles (34,600 km) on the clock. It’s finished in Grand Prix White, it looks awesome and it’s expected to “bring home” between £150,000 and £170,000 ($230,239 – $260,938).

Next on the list are two 911 996 GT3 RS models. With only 140 right-hand drive examples manufactured, you can safely bet these cars are very rare. Both have very low-mileage from new, both are white and both come with the iconic factory-Porsche decals. The white and blue example had a number of driver focused upgrades during its 26,889-mile (43,273 km) life, but the real superstar is the white and red variant, as it’s only covered 3,277 miles (5,273 km) from new and it was originally delivered to Porsche in Hong Kong. That’s why it’s sensibly evaluated at £145,000 – £165,000 ($222,517 – $253,209). Yes, that amount of money gets you a 996.1 GT3 with a 3.6-litre, H6, developing 359 hp.

Completing the inventory are two 997 GT3 RS’ – the last ever manual, water-cooled RS produced by Porsche. The first one is a classic “textbook” 2007 997 RS with a striking orange color, contrasted by black “RS Script” and decals. Having only covered just 5,527 miles (8,894 km) from new, it’s currently expected to fetch anywhere between £130,000 and £150,000 ($199,498 – $230,190). Mind you, the second 2010 “gen 2” white example is an immaculate alternative, with only 1,500 km on its odometer, but that doesn’t make it more expensive. Both cars sport a 3.8-litre flat six, but the 2010 model has the new and improved powerplant which boasts 444 hp – 35 more than the previous gen’s power figures.
