I have a C-Max 1.6 TDCI Ghia,'04 plate.
Bought it 16 months ago,58k on the clock,its now done 71k,& in that time not had a problem with it,it returns 54-58mpg on motorways,(altho have had 61 mpg on a trip from Lancashire to Keswick & back!).
Ref headlamp bulbs,to change them its just a matter of removing a torx bolt,pushing down on a retaining clip located at the bottom of the headlamp,& it pulls straight out.Fitted a HID kit to mine,which improves the lighting 100% over the standard candles.
Now,onto the important stuff......carrying bikes.....
I run the car,say,95% of the time as a two seater.i.e.with all 3 rear seats removed.Its easy to do,just tilt the backrests forward,then tilt the seat assemblies forwards,flp two red levers,& remove seats.(They weigh a LOT,I was surprised at how much,why spend £100's chipping it to improve the power?,just remove the seats to improve the power to weight ratio!!)
I get the bike in led down,without having to remove the wheels,but as is more often,travelling 2 up,with 2 bikes,I just remove the front wheels,& stand the bikes up.If 3 of us need carrying,i just refit one rear seat,& 3 bikes go in as before,stood up with front wheels removed,& all ride kit piled up behind the rear seat.
Also,i've fitted a "hatchbag" http://www.hatchbag.co.uk inside the rear of the car,protects the carpets,side trim,door cards etc from muddy bikes.(Altho they had to specially order mine,as up until I ordered it,they didn't make one to fit a C-Max that has its seats removed).
As for driving,its v v comfortable,driving position is great,went from Lancs up to Fort Bill last May,2 up,d/h bike,x.c. bike,3 days worth of kit,tools,spares etc,just stopped once at Carlisle services,& when we arrived at Fort Bill felt as fresh as when I had got in the car back home,55mpg for the return trip.
As you may have sussed,I like this car a LOT!
