Hi and welcome to LOC :)
There aren't really many issues as others have said, cambelt is 60k or 6 years.
The CD players are prone to failure, so check it's working or factor in the cost of replacement when buying the car.
As already mentioned the Sport is only a manual, so if you want a Sport you can't have an auto. I have an auto and it's fine, the gearbox is a good one and it's happy to kick down when required, changes are smooth and there's no lag.
However the auto is worse on fuel, and is a fair bit slower than the manual, so I'd recommend testing both if you are unsure and see which you prefer. I average about 23-24mpg out of my auto, getting any better out of it would require some careful driving.
