I used this firm for a replacement MK2 Mondeo bumper for the chap whose car I managed to crunch.. 
In this instance it was a special offer at £89.99 for a painted OEM bumper....great price! The downside was a long wait for delivery....3 weeks in total...nevertheless, I have to say they did a great job of the spraying!

MK1 Rover 75 bumpers here: http://www.everycarpart.co.uk/rover-199 ... _6120.html
MG....ummmm...thus far I can see no indication that they do them...shame that..
They also do any other body panel....might be useful!
