Is worth buying a Pre Owned Jaguar XJ

I’ve been looking a Luxury Car for Rental car Business. I’m pretty young and i own 2 business. I’m looking to start another business that is Rental Car Business. So i was looking for few options. Mercedes C-220D W205 (2015), BMW 520D F10 (2014) or Jaguar XJL (2012). And Jaguar is always been my favourite i was in mad love since i saw it in Nat Geo Supercars when i was a kid and i still love that car a lot. And i found one for 11.4Lakhs Negotiable. Jaguar is driven 56,000kms and painted in special Cashmere colour. On paper car seems to be in great condition and owner is selling it directly and he’s also a business who owns other cars such as Rang Rover Evoque and Audi Q7. So i wanted to know what are possible issue i can face with this investments from your real experiences and should i even go for it or invest in more expensive car that is MERCEDES C220D W205 2015-17. Please help me out.
