Living in Greece, do you really need a hard top. I would have thought you would be driving with the roof down, every day?
KMS also do this though not sure how much. If you're interested I can get you there details. I know the guys there and may be able to do you a discount. Not sure how much shipping cost would be though.
Unfortunately, even with any discount I doubt if you would save a lot of money buying from UK as the shipping cost may off set any savings:-(
