I wouldn't buy another Jaguar that has been in the clutches of Paragon, however fleeting. They appear totally unaccountable to anyone.
Whilst in their 'tender care' my car ended up with wheels taken from another car . A car that was one year older. I discovered this when the tyres were replaced and two different registration numbers were found on the rims.
For some reason they also replaced the XFR aero skirts with standard items. No idea why. Paragon tell me they keep no records of work done and I need to ask my dealer, the very dealer who pointed me toward Paragon in the first place.
Clearly uninterested JLR say contact Paragon

...........Jaguar CRC say the only 3 words they know 'contact your dealer'
I'd get more information if I contacted Area 51 and asked for details of captured alien spacecraft.
