The official currency is the Colon (in honor of Christopher Columbus - Cristobal Colon in Spanish). Notes are in denominations of 10000, 5000, 2000 & 1000 colones. Coins are 500, 100, 50, 25 and 5 colones (also in circulation are old silver colored coins of 5, 10 & 20 colones). As of January 2007 the exchange rate was 517 colones to 1 US dollar. Until September of 2005 the currency was devaluated at a rate of 9% per year because of the Central Bank policy. In October of 2005, the Central Bank began to allow the colon to float within a crawling band, with the idea of eventually allowing the market to decide its value. Through January of 2007 the colon has held its value against the US dollar. The Central Bank is still monitoring the currency, but the band will allow increases slightly each day, so at some point they will implement the next stage of the plan. You can find the historical and current exchange rates on their site - http://www.bccr.fi.cr. The state banks and private banks post their daily rates in real time on the site and the reference rate is an average. You will get a better rate exchanging currency at the state banks, but the private banks are more convenient and speedier.

Cost of living - Automotive
In general, parts are more expensive here and sometimes difficult to find. On the other hand, labor is cheaper. So a trip to the mechanic here might cost about the same as what you'd pay in the U.S.

Cost of living - Household
One of the great things about living in Costa Rica is that you can afford to have a maid and/or a gardener for very little money. By law, you must pay your maid $140 per month, plus food and lodging. In return she must only work 12 hours per day (up to 16 hours if you pay overtime). You must give her 1 hour off each day, to coincide with a meal time. You also must give her 1 half day off per week, a half day off on holidays and 15 days of paid vacation per year. You should also enroll her in the Costa Rica Social Security system, so you would deduct 9% of her salary for this tax, but you must also pay 11% to the "Caja".
