I feel that the Jaguar XJR5 is the best racing Jaguar. Group 44 did an incredible job and the XJR5 was designed and built in between two racing sanctioning bodies therefore compromising its design to be legal on both sides of the pond. Group44 was always very professional and extremely generous to the fans and they were of course the best looking cars ever!!
Hey, I've got to throw some love to those TWR prepared XJS cars. If nothing else, they at least embarrassed Porsche and BMW on more than one occasion and stole from them the European Touring car title. Not only that, they proved that the XJS had a racing pedigree and really could be racing cars.
