XC70 2005 Life Expectancy

[narelleg]

Hello. I am new to the world of the Volvo and require some experienced advice.
I am looking at purchasing a second hand Volvo XC70 2005 model. It has very high kilometres - 218,000 (136,000 miles). Has only had one owner and has been looked after very well, regular services etc but I have been told it has a manifold with a crack so that will need to be replaced.
I have always been told to look for cars with low km's, hence my uncertainly and just want to know if I should pass on this car? It is a lot cheaper than many advertised (obviously due to the high km's) but I do know the seller, a very honest family.
The car has mainly done country km's, also an advantage I think.
So I would love your opinions on the car if you would not mind. I am in Melbourne Australia.
Many thanks in advance
Narelle
