In January, Scion forecasted that they would sell at least 120,000 cars. Now, they're revising that estimate to more than 140,000 although they believe it could be as high as 150,000. The only problem is that they can't build the cars fast enough. Last year, Scion sold 741 cars shy of 100,000 — the first year they sold nationally. Those kinds of growth numbers seem remarkable for such a new brand and accounted for more than half of Toyota's 10 percent increase in US sales. Scion's average sale price of $17,515 is thousands under the current average transacton price for a new vehicle ($24,520).
