Hey Robbsy,
Welcome to the Zclub!!!
You clearly have good taste in cars.
The 240 is of course the one people look for as the golden child but it didn't worry me at all to have the 260 and I found the engine a lot more tractable and willing low down.
The 280 was never a UK market car but a good car in its own right if you change the crazy large bumpers.
Are you bothered by RHD / LHD?
What sort of budget are you looking at?
Are you looking for a project car or a sorted drive and polish car?
Give us more details and ask lots of questions - but don't just buy the first one you see! [emoji6]
