I bought my 2010 Fiat Doblo 1.6 Maxi van for £1000 with 100k miles a few years ago as the previous owner thought headgasket issue, but on testing it proved to be the oil cooler allowing oil into the radiator. Also had black smoke which turned out to be a EGR pipe gasket leaking on inlet manifold.
I also have another crew version I use for spares which I paid £280.
