The one in Cork may not be that bad, needs to be looked at by someone who knows their 155s.
The bonnet not closed on one side is a quick and easy fix, the exhaust on at an angle is not ideal but probably harmless.
Also it IS red, which is a bonus with the 130 coloured cars.
The main concern is doing the clutch, not an easy job on the 155 in my experience and I've only done the 1.8 and 2.0L clutches. Cant imagine that the V6 is easier and I'd imagine the subframe woudl need to be loosened off.
I've thought about bringing one in from the UK too but the total cost of getting it here and VRT etc just doesn't make it viable imo.
On the other hand the V6s dont come up for sale much over here......
