Which one to keep D3 or D4!
Hi all, new here, but had a couple of D3's over the years and my wife has a D4.
I've recently bought her a RR Sport and now have the dilemma of which one to keep for myself/work. My current D3 is a 2007 that I've had for 7-8 years now, bought on 40k and is now just coming up to 100k. It's had no expense spared on it over the years and is pretty mint. But we also have a 2012 D4 which we've only had for a year or so, has FSH but has 125k on the clock. Now my gut says that the D3 is probably going to be more reliable, but the D4 is such a nice drive. What would you all do??

keep both of them i have a 2005 d3 and a 2013 d4 both great cars often think the same as the d4 did 340mls last year but the d3 i think is going to have tin worm problems next mot time so that will prob go as the d4 only has 70000mls on it so should last another 10yrs or so
i'd get shot of the rr but thats just me please excuse any grammer/punctuation mistakes,i'm thick,thankyou
current vehicles 2005 d3 2013 d4
I agree entirely, particularly with eightfoot with regard to the RRS

This is simple. Keep the D3 and D4 and get rid of the RR Sport. After all it was only ever aimed at drug dealers and footballers. D4 HSE EU6 (Known as Jeeves)
New Defender L663 110 SE (known as Noddy!) Sold
Sold Volvo XC90 R-Design (known as Basil)
Sold - D4 HSE (Known as Gerty)
No longer the Old Buses original owner
231,000 miles and counting
05 S manual owned from March 2005
D4 Face lifted
Still original injectors and turbo
V8 Front brakes
BAS Remap, Allisport Intercooler and deCat
EGRs blanked
T-Max split charge
Hanibal Expeedition rack
Prospeed ladder
Duratrac tyres
IID BT
BAS FBH control

Ho !!
Lovely to have the choice ))
No question, now you've had time to discover your D4 is not a "pup", you should keep it.
D4s vs D3s - there were a SMALL number of regressions but most of the improvements applied to the D4s were good and worth having.
Have a good indy listen to the D4 engine before your final decision, then keep on top of timing chain maintenence/renewal.
I agree with advice above, also keep the D3 and ditch the RRS !!! Then run both until JLR produce a worthy successor to the D4.
But whichever you keep (D3 or RRS), get them both undersealed before next winter.
Cheers ))

Haha thanks all. Completely agree with the RR Sport image, much prefer the Disco for when people see us. However the RR Sport is the L494 3.0L petrol supercharged - which is an superb drive, another league on the Discos. Interesting that you would keep the D4 over D3. I had a good hunt around when we got it and it seemed to me like the early 8 speeds you couldn't find spares or repair, whereas the 6 speeds and the Euro 6 seem to come us? This may just be coincidence and wishful thinking!

D3 or D4 to keep
I guess that depends on the engine:
Petrol - I think the 4.4 D3 V8 is more reliable compared to the 5.0 D4 V8 as the newer engine has gone back to Plastic Chain tensioner that already killed the first 4.0 Jaguar V8 and suffers from the typical direct injection issue of Carbon Buildup on the Inlet side.
V6 supercharged Petrol - no idea how it performed in the D4, but in the F-Type Jag it had several engine failures.
Diesel - probably the early 3 Liter V6 are most reliable before the engine got more and more systems added to generate cleaner exhaust emissions.
and what I would not keep at all is a D5

Given where you live I would take a good look at their undersides - particularly the rear sections around the suspension mounts as that is what killed our D3 in the end.Currently 2009 Disco 3 SE, 2013 MY D4 HSE and 2016 D4 SE
Previously:
TD5 Defender 110 CSW (230k miles)
300TDi Disco 1 (289k)
4 RR Classics (300-350k each, 2 manual, 2 auto)
110 V8 CSW (220k)
S3 109 hi cap pickup (ex RN)
S2A 88 Safari SW with lpg conversion (bloody lethal)

Keep the D3 for when you need the big boot and don't mind driving a bus or having people think you're selling knock-off tarmac. And keep the RRS for when you want to be reminded just how good a large SUV really can be to drive both on and off road. Simple. Visiting from rrsport.co.uk
2012 RRS SDV6
2008 RRS TDV8
