So I've had my X260 for a couple of weeks now so thought I'd post my comments on a comparison with my gone X250
First off good points;
The ride quality seems a lot more forgiving. (Still on 19" rims)
The chassis is a great improvement coupled with the more supportive seats it feels like it corners flat.
The turn in is much much better though this could be down to newer rubber
The infotainment is much better
The 2.0D engine is a peach - nowhere near the smoothness of a V6 but how could it be? I thought I'd miss 60BHP but TBH I don't. The take off from start is impressive. It feels like it's got loads of torque and coupled with the 8speed its well suited. I often felt the 6 speed held on to the gears for too long, so much so, I found myself using the paddles to change up sometimes!
You can only really notice it's a 4 pot when slowing to < 10mph or sitting idle, but most of the time it's off from start/stop so it's the smoothest engine in the world!
When giving it some beans, yes you can hear it but it doesn't sound horrendous, just working.
The remote control app that allows you to check if the car is locked, alarmed, check fuel level, mileage, recent journeys, mpg, remote start to set climate is brilliant.
Rear view is much improved - mainly due to the relocation of the high level brake light- meaning there is no bump on the rear shelf
Speed sign recognition is cool and works pretty well.
Heats up quick
Stop/Start works well with one battery.
Like the TPS where it not only shows the proper pressure, but the current
Like the info display which is configurable I got it currently showing ave mpg, ave speed, miles to empty etc
love the heated steering wheel
Boys love the rear heated seats
Like the privacy glass
Loving the mpg
Charging/jump start points now under bonnet ala XJ/XE
Like the dash change from white to red when in dynamic mode - nice touch.
Satnav seems good with 3D mode, haven't used it anger yet though.
voice control seems ok, seemed to understand me ok.
Boot is slightly bigger with no cross member bar to overcome. Includes shopping hooks.
The interior mirror is either bigger or lower down due to the forward facing camera (or both) means I feel like I can't see out of the passengers side properly.
The single wipe of the windscreen requires moving the stalk from auto, to off, to wipe, so if you want a single wipe without washing you have to move the stalk down two positions then back up two again. I liked my old pull to wipe function
Bog standard audio, is ok but need more bass - I've a plan for that.
Sills are quite wide, meaning you seem like you have to step into the car rather than getting into it.
The rear camera either doesn't have the low lux capability of the x250 or it's a lower resolution
Things I miss
No mirror reverse dip
No keyless entry
No fold down rear seat. Didn't use it that often, but came in handy a couple of times. Will need to investigate if this can be modded.
No memory seats/mirrors/steering wheel, but I do have folding/electrochromatic. Partial electric seats. Manual steering wheel adjustment.
As you can see not many negative points, some things I miss but will get over it. If I had to analyse the time I adjusted the seats/mirrors/steering wheel I could forgive not having them now...
