[Lord of Hog]

Look for coolant leaking into the V (take off the acoustic cover to have a look). Normally only the result of the thermostat housing O-rings failing but looks sufficiently terminal if you want a bit of leverage on price. Remember that the coolant needs to be checked and re-filled in its own special way. Be prepared to pay between £500 and £700 for the belts to be changed and do not be tempted to skimp in this department. Don't expect more than about 25mpg under normal use unless you do a lot of long distance.
