"Clunk" from rear of Vantage manual

[Z4MFarmerpalmer]

Eve all, the last couple of times I've driven my 55 plate manual Vantage I have noticed an audible "clunk" when coming to a stop, say at a junction and then again when pulling away again. Not heard it whilst in other gears etc. Any ideas what this could be?? Sounds like a mount or something has gone on the driveline. Mileage done 60,000 so its no garage queen and it is driven hard.

Could be a number of things - not sure what the gearbox mounts are like, but I'd start with undertrays and make sure something hasn't got into it and is rattling around.
