In 1991, Walter Lechner commissioned Reynard Motorsport to build a sports 
prototype for the Division 1 class of the Interserie. Called the 'Lechner Spyder SC91', the car was powered by a 3.5-litre Judd V10 engine similar to that used in Formula 1. Lechner drove the car himself, usually under the 'Walter Lechner Racing School' banner, and gave it its debut at the second round of the 1991 Interserie season, the Nürburgring Supersprint, retiring after five laps due to a vibration. Two weeks later he competed in the next round, held at the Osterreichring, taking 5th place in the first race and 6th in the second, resulting in him being classified 5th overall. At the next round at Brands Hatch, Lechner finished 3rd in both races but was classified 4th overall. He was unable to start the Most round but returned for the Siegerlandring event. Lechner struggled in the first race and was only able to finish 10th; however, he finished 2nd in the other race and was classified 2nd overall. The final round of the season saw a return to the Osterreichring where Lechner took 2nd in the first race and 4th in the second race, taking 2nd overall. Lechner finished the season in 4th place, the best of the non-Porsche 962 drivers.

Lechner retained the Spyder SC91 for the 1992 season and ran it in the Mugello season opener, retiring from the first race. Despite taking 4th in the second race, he was not classified. The series then returned to the Nürburgring where Lechner retired 
from the first race once again and did not start the second. He switched to the Lola 
Horag for the next two races, and an attempt to enter the Spyder SC91 in the fifth 
round of the season, held at Most, was unsuccessful; as a result, he retained the Division II Lola Horag for the rest of the season. Lechner finished 19th in Division I and 2nd in Division II.

In 1993, the Lechner Spyder SC91 was rebuilt with new bodywork and re-christened as the 'Reynard Spyder'. Walter Lechner was still its owner and driver, and the 
rebuilt car, now run by the Sebring Auspuff Team, was his choice for the 1993 Interserie season. The rebuilt car's debut was a mixed bag; Lechner took its first ever victory in the first race of the opening round, held at Jarama, before a retirement after 14 laps in the second race dropped him to 9th overall. It was a similar story at Mugello, Lechner retiring following a collision after six laps in the first race, before 7th in the second race secured 14th overall. The Interserie then moved to Most where Lechner retired from both races, although he was classified 14th in the second. At Siegerlandring the car came good again; Lechner took 2nd in the opening race and 
won the second race, taking 2nd overall. The penultimate round of the season was 
held at Donington Park; Lechner took 3rd in the first race and another victory in the 
second, which secured the car's first overall win. The Osterreichring held the final 
Interserie race of 1993, where Lechner's 3rd in the first race and 3rd in the second secured another 2nd overall. He finished 3rd in the Division I driver's standings, behind both Kremer CK7 Spyders.

Lechner favoured the Lola Horag HSB for 1994 but would use the Reynard Spyder one last time; in the final round of the season, held at the Osterreichring, where he won both races to take the overall victory. Despite this, he opted to use the Lola Horag HSB for the next couple of years and did not race the Reynard Spyder again. That one race, however, was enough for Lechner to take 9th in the Division I championship for 1994 (he had already won the Division II championship prior to that final race).

Lechner retained the Reynard Spyder and ran Josef Neuhauser in it for the 1997 
Interserie season; the car was now known as the Reynard Horag, and the team as 'Dark Dog Lechner Racing'. The opening round at Spa saw Neuhauser finish 2nd by just over two hundredths of a second to Karl Hasenbichler and his Penske PC 18. At Most, Neuhauser finished 5th in the first race and 2nd in the following race to claim 4th overall. At the A1-Ring, Neuhauser took his first victory with the car, beating Karl-Heinz Becker's modified Minardi M190 by 21.4 seconds. The fourth and final round of the season was held at the Hungaroring; Neuhauser took 2nd in the first race and 3rd in the second, securing 2nd place overall for the weekend. Neuhauser won the Division I drivers' title for 1997, beating Ranieri Randaccio by 11 points.

Neuhauser continued with the Reynard Morag for the 1998 Interseries season, now entered by Achleitner Motorsport. The first round of the season, held at Most, saw Neuhauser struggle, and finish 5th overall (3rd in Division I) and last. The second round was also at Most, and here Neuhauser took two victories en route to winning the round outright. Next up was the A 1-Ring, where Neuhauser won again, this time by 15.7 seconds from Karl-Heinz Becker. Neuhauser finished the season with another victory, this time at the Hungaroring, and retained his Interserie title, beating Becker by seven points.

The Reynard Morag was not used in the first round of the 1999 Interserie season, but 
Neuhauser ran the car in the second round, held at Most. Now competing in Class 3, he took 2nd in the first race, and 3rd in the second race. Next was Grobnik where 
Neuhauser won the first race and followed this with 2nd in the other race. The final 
round of the season was held at the Hockenheimring where electrical problems 
prevented Neuhauser from starting the first race. He recovered to finish 3rd in the 
second race but slipped to 3rd in the driver's championship, finishing 1.5 points 
behind second-placed Michael Schuster's Argo JM 19C. The car was retired after the end of the 1999 season. It no longer has the Judd engine but is currently fitted with a 4.0-litre BMW V8.

The foregoing history was taken from the detailed report prepared by Ingenieurbüro Ramler of Meppen Germany, which accompanies the car together with its OSK Wagenpass. The current vendor acquired the Lechner two years ago and advises us that it has seen recent use, is race ready and in good condition.
