I agree seems to be the way with most modern cars I'm afraid, If you are not on hard level ground in perfect lighting then I'm afraid it's a job for the breakdown services as far as I am concerned.
Moan, moan, moan.
My Modus is my 34th car but I have never seen such an awkward spare wheel cradle in my life.
Today I changed one of the wheels for the first time and luckily it was on my drive with a good surface, plenty of light and a steaming mug of coffee.
I seriously doubt an oldie could have done it at the roadside, no wonder so many people these days call out the rac/aa boys. Up untill now I would have felt a right wuss calling someone out for a flat but not anymore.
Laugh? I nearly read the handbook!
Tho they will not come to a flat/puncture unless you have the appropriate cover .
