Nice buy,
There are a couple of things I will tell you to monitor with the 2.2l Diesel mate.
Here they are....
1.Keep a check on the coolant, every month.
2.Keep a check of your garage parking spot for engine oil, poke your head under every month and check the underneath for ANY oil leaks.
3.If you get it serviced anywhere other than a holden dealer, DONT.
Yeah yeah, I know but there are some good ones out there, just got to make sure they are on top of their **** thats all.
And if you need ANY advice on it hit me up a PM and I can tell you anything you need to know about these.
