nice car, you should have come along to Stirling last week with Sean
I added fogs to mine, you get them on ebay quite alot and its the same fogs for mk1/mk2 ZR and mk1/mk2 ZS, you should pay around £50 for them, the wiring should be in place already.
The only bad part is you need to take the car to an MG garage or somewhere with the machine (T5 iirc) and they plug it in and update your cars computer, they wont function other wise, and to make it worse they charge what they want to activate them, so could be up to £70!
To get round this, I got a wiring kit from ebay (£9) and have them hooked to my full beam. worth a thought.
The advantage of the 110, is there is space behind the bumper to fit your fogs without having to remove the whole bumper, they fit easily with a few screws holding the blanks in place.
Hope that helps? here are some fogs....
