Errr, that is not true, some "slight" bias there.
Engineers have civil qualified sparkies, plumbers, joiners and project managers for example. REME have veh mechs, airframe techs and courses that gain upto degree level. Signals have trades that gain CCNA, Network admin, DB admin and again courses upto degree level.
Depends more on the trade, does it not?
You did not get any NVQs, BTEC ONC/OND/HNC/HND, CAT C/C+E (host of other driver quals)?
REME -(Royal Electrical Mechanical Engineers) like you have stated are probably the best part of the Army to be for gaining quals that will help you in civilian life yes. You can probably get a job in a garage as a car mechanic for example of the back of leaving the army as a VM (vehicle mechanic)
As for driving quals, yes most people in the Army get driving quals including C & C+E, driving quals arn't exactly something to write home about? 80% of people over 25 in the UK have a valid driving license.
I am actually in the Signals, well was, I got a few NVQ's (Level 2) which is garbage. I did a very high spec job, I was a Spec Op, all my qualifications are either 'classified' or 'military' quals. Much like the rest of the qualifications you get out of the Army.
I would hardly say it's worth joining the Army for a driving license and maybe an NVQ :/
