Recently test drove an '06 Tc and an 06 Civic EX Coupe back to back, pretty close on price and features, but the quality on the Civic seemed to be higher, felt like better fit and finish. I"m 6' 2" and had a hard time getting comfortable in the Tc, but was able to get the Civic to fit me better, more quickly. The seats in the Civic I liked much better, too, the seats in the Scion, while they looked well bolstered were way too squishy and didn't provide anywhere near enough support. I know you weren't asking about the new generation of Civic, but it might be worth a look (I personally like the looks of the new Civic a lot more than the '05 Si). Oh, and the result of my test drive? Deposit down on an '06 Si with Nav in Rallye Red....
