I have a 2010 Scion xB and my wife had a 2009 tC. We bought them both new. She upgraded to the 2014 Mazda6 when they came out. But we both love/d the scions. Not 1 issue between the two of them other than crappy mpg. Mainly because they only had 4-speeds. The newer tC's have a 5-speed. I use the xB to tow my track bike around, some of you may have seen it. I have 63,000 miles so far. Only cost so far is brakes, oil and tires. But both of our scions used the corolla 2.4 engine. I doubt they used a mazda chassis for the iA as scion is a toyota sub-brand. But they may have.
