There are daily train and bus connections between Athens and Istanbul via Thessaloniki. The bus is much faster than the train. You can also travel by bus to Syria, Georgia and Iran, and by train to Armenia. Turkish Maritime Lines runs car ferries from Antalya, Marmaris and Izmir to Venice weekly from May to mid-October. Private ferries run between Turkey's Aegean coast and the Greek islands.
Buses go everywhere in Turkey frequently, cheaply and usually comfortably.
If you're driving around Turkey, you'll find mechanical service easy to find and relatively cheap but dealing with psycho drivers may be more of a problem. Driving in cities should be altogether avoided - traffic is terrible and parking impossible. Car ferries can save you days of driving and offer the opportunity to take a mini-cruise along the Turkish coasts.
