I honestly would not even bother with the UK. A lad from my work is emigrating to aus to do the same job which pays better than over here.
The motor trade is dead at the minute and to be fair a load of garbage. 70% of the job is now paper work, employers are only interested in pieces of paper that says you can do the job which is a load of crap. I've seen many people come and go at our place with all these flashy qualifications and they can't even do the most basic of stuff but yet they still get payed more than me cause a piece of paper says they know what there doing
Do yourself a favour, stay where you are.
