I sat in the entire Scion lineup at the auto show. Though the xA and xB are complete embarassing shit mobiles, the tC was pretty decent. I'd say it is definately at or near the top of it's class (aka econo-boxes). Only being offered in a 2 door probably hurts its sales, but IMO gives it a sportier appearance to buyers.
Sadly, all these economy cars are getting to prices that I could never justify, at least new. When a tC costs what a decent mileage, good condition 6 year old C5 costs, there's no way I could sport the wrong wheel drive car.
But hey, if it wasn't for people buying new cars, I wouldn't have any used cars to buy. (have never purchased new, and have no plans....I'll let someone else eat the depreciation).
