If he's moving to the south he won't have the MOT to worry about because the MOT doesn't exist! In southern ireland its called the NCT.
Some stuff pulled off the web about it -
The NCT is a National Car Test carried out on all cars in Ireland that are over 4 years old. It is carried out every 2 years. Cars over 30 years old do not have to be tested - which seems a bit scary to me.
The NCT was only introduced in 2000 - before that you could have any old wreck out on the road and nobody could do much about it.
The tests are similar to the MOT in the UK. Unlike the UK - the NCT tests are not carried out by garages - which is probably a good idea because if a garage does the test there is always the chance that they will find something wrong just so they can then charge you to fix it. NCT testing centres just carry out the test. If the car fails it needs to be repaired at a garage or by the owner.
The testing fee is currently €49 euro. A retest costs €27.50 - but must be booked within 21 days of the original NCT test otherwise you pay the €49 again. You must bring your registration certificate with you to the NCT test. Minor failures such as registation plates or wiper blades will not require a retest fee.
The NCT test is more concerned with safety and gas emissions than with road worthiness. Exhaust fumes are tested - as are headlight alignment, seat belts, tyres, brakes, windscreen.
An NCT "disc" is issued which must be displayed along with your tax and insurance discs in the car windscreen.
