Ok First thing... Best place in my opinion to wash your car if you've no hose at home + too lazy is the Tiger wash on the N11 - Not the massive drive through one but the Hand Power washers beside... Why ? Well because you can put in 1 x 1 euro.. Shampoo your whole car(Loads of hot suds) Then you can use the brush without paying to get a good scrub all aroudn the car / wheels etc. Then pop in another 1 x 1 euro and use the soap brush properlyto scrub the worst bits. Another 1 x 1 euro at the end to rinse off and thats 3 euro for a spotless car. Another 1 euro if you want a bit of wax and your pimped.
Setup a server in work running a little mobile app if anyone wants to try it. It basically pulls infor from irishfuelprices and some up to date traffic cams / carpark spaces and mobilises it. i.e you can check this anytime from your mobile phone.
