We also needed to get our international drivers license changed into a SriLankan driving permit which cost 2800 rupees (US$24) valid for 1 year.
We get about 25km per litre and petrol is about 160rupees (US$1.50) a litre. We fill up every morning as the bajaj only holds 8 litres and on average costs us between 500-800 rupees a day to fill, depending of course on how far we drove the day before.
Repairs - knock on wood, so far the only repairs we have needed is to fix the brake light, which cost a whopping 60 rupees (US$0.40). Hey big spender~~!
eating and drinking
Mostly we eat at "hotels" as restaurants are called here. We usually get 4 paratha and a thali (a mix of dahl,curry and 2 veg), along with 2 cups of tea, for between 150-250 rupees (US$1.20-2.30).
Lunch and dinner is the same. Gypsy loves fried rice and Kothu Roti so we eat alot of these too. Prices are around the same.
It's really interesting how the food culture changes so much here. In the north string hoppers are for breakfast, but in the central highlands, they are for dinner!
Drinks - Water is pretty cheap, about 70 rupees for 2 litres. Fresh fruit juice ranges from 150-200 rupees, and tea is between 30-40 rupees a cup. Ginger beer (super delicious and refreshing) is 50-70 rupees, pre-mixed juice is expensive! 110 rupees for 500ml!! Coke etc are 50-70 rupees, and last but not least, beer (only available from dedicated "wine stores" usually with a compulsory deposit of 20-30 rupees for the glass bottle) are 150-200 rupees for 700 ml. According to Roh, the Lion is quite nice but the "Bison extra strong 8.8%" tasted like petrol.. Arak is just gross.. cheap but gross...
Taking all of this into consideration, the entrance fees for everything are just ridiculous. The smallest temple or national park is at least 1000 rupees each!! As much as the government thinks it is making lots of money this way (which I'm sure it is from the package tourists), it's also losing alot of money from the backpacker tourist and I hope they wake up to this soon and re-instill the historical SriLanka pass, so us on a budget can afford to see all of the sites Sri Lanka has to offer too.
