Omega 2.6

[Jimmy No Hands]

Off to view an Omega 2.6 auto estate later, just as a general winter shed, tip type vehicle. It's very cheap, fairly low mileage. I have no idea what I'm looking at mind, how are these 2.6 units for big miles and general durability? It has had the water pump and cam belt done apparently, is there anything else to look out for? Concerns being the autobox really and it being rendered useless in an expensive manner. Any idea of running costs would be appreciated too.

Many thanks!
