I myself have the same doubts despite trolling these forum pages and can sympathise with you on the purchase or thought of purchasing one.
What i do find strange though is that you are comparing reliability to an X5 which has had similar reliability stories about it.
It would appear you wont use the D4 to its abilities, why not just go Lexus RX if you are considering the X5 for reliability?
A recent publication by JD power doesnt help the cause when it shows an inordinate number of faults per 100. 2016 US Vehicle Dependability Study VDS | J.D. Power . Whilst its for the USA, it reflects the refreshed line of cars LR has produced from 2013. What is unknown is how reflective it is of the D4
Yes, i read splendid stories here about how well the D4 performs and how many kms it has done but yet first hand feedback from friends who own D4s have consistent issues with their vehicles.
One thing that is obvious is that you will always get a biased answer from a vehicle forum. Read the pages and list down all the faults people have had. Put a dollar figure next to it and start adding up.
For me, my heart won over my head and i'm negotiating on a price.
