Report Abuse. Hello, Yes, 'biannual' means twice a year. It is biennial (note the spelling is ONE letter different!!!) that means every two years. You can also use the term semi-annual for twice a year. Now I was ready to tell you different and then I looked it up in this source: http://www.bartleby.com/68/34/834.html. This is always a great source for many language questions: www.bartleby.com --I was using the 'usage' section for this question.
Fortunately, depreciation does not continue at this rate, but it is still faster for new cars than for old ones. On average, a new car will lose as much as 19 percent of its value in its first year of ownership. That means that your $20,000 new car will be worth about $16,200 after just one year. With each successive year, the rate of depreciation decreases significantly. Check out the car depreciation chart to see how a new car may decrease in value over the first five years.
Dealers drop the price of a car an average of 1.32 times per month, but some months it happens more, and others less. Between July and October dealers drop the price of their cars most frequently, whereas January through March dealers drop their prices least frequently. As the volume of sales increases in the summer months, dealers seem more willing to drop the prices of their used cars. The average price drop on a used vehicle is actually 5.42%.
