Hi Sirrah, welcome. I don't believe there is a change of design forthcoming for the F-Pace, but there are some on this forum that are better informed than I am on such matters. Like you, I am an ex-Range Rover owner. I had a Full Fat RR, plus 2 Range Rover Sports. This is my first Jaguar and for me, it was the best move I ever made. I find the F-Pace is smoother and more sporty than the RRS - maybe be not as good on REAL 4X4 routes and lanes, but how often do you venture fourth into the wastelands? The FP is a great vehicle in the snow, which is why I continue to buy AWD vehicles. The only thing that took me a while to get used to was the driving position. You are not sat on top of the vehicle in the "command driving" position, you sit in this car, right in it its cockpit. Held firmly in position by the seats which are equally as comfortable as the RRS.
Don't know about the 240D engine, but the Ingenium range generally get good reviews. As for optional extras, these are very personal (you will have experience from your RR - the Jaguar ones are the same. If not in form, then in function! The only thing extra I would not live without in ANY car now, is the heated steering wheel!!! There does seem to be some difference in the build quality of Jaguar (for the better), which is surprising as they come off the same production line in Solihull as the RRS! I have had no problems with my car at all other than it needing an ICTP software update. That will soon be a thing of the past as JLR inform us that we will be able to receive OTA (Over the Air) updates in the not too distant future..... believe it if you will!!
Why did I change from RRS? For me, it ceased to be value for money. It is over priced in the first place then after 3 years it drops a third in value, crazy!! My F-Pace was the closest in spec to the old RRS I could get with a petrol engine, yet it was ÂŁ12,000 less than the equivalent Range Rover Sport. I do not see ÂŁ12,000 difference. I hate the Velar, 'nuff said!
Get down to the dealer get a weekend test drive and see if you can see the difference in value.
Best of luck.
