Note that I'm referring here to the 2010 Focus Mk2.5 (facelift MK2) that I've recently bought. I can't comment on the Mk3 as I haven't seen one. We still have the MK1.5 that we bought six years ago and comparing the two I think the interior design of the Mk2.5 is very much inferior.
First the instrument panel looks really tacky. It puts me in mind of a childs toy. Ok, obviously some compromises were necessary to make room for the message panel but the fuel and temperature gauges are pathetically small and the chrome surrounds to the instruments and the silver infill just look cheap and blingy.
Next the console. Here again there's too much silver. It just looks cheap. The cover for the power connector sticks up like a sore thumb. The cup holders have got smaller and are pretty much useless.
The door pockets have also got smaller and the low position of the door handles prevents them from being used for any tall items, such a road atlas. The window and mirror controls feel a lot less robust and relocating the mirror control to the door handle is in my opinion a backward step : the combined switch/joystick on the inside of the mirror mount is much more practical for adjusting position while in motion as you don't have to look down.
In addition to those individual niggles the overall styling of the interior of the older car still looks fresh compared with the rather staid and unimaginative look of the new one.
I even find the exterior styling rather bland compared to the older car, which was quite ground-breaking in its time. I would accept the Mk3 looks a lot better although I'm not convinced by the rear lights - too far-eastern in concept for my taste.
So you might ask why I bought the Mk2.5 rather than another make and the answer is that I find it fun to drive with precise handling and a good clutch and gearbox. It feels much tauter on the road than the Mk1.5 although that's not really comparing like for like as the old one is an estate and has done 105K so it's running gear is probably getting a bit tired. Also it's a heavy old diesel lump whereas the new one's a petrol hatch with only 24K on it.
So have I opened a can of worms with these observations? What do you other people think?
