I understand what you are saying. I'm not sure what Japanise company spawned a premium line first. Lexus, Acura, or Infinity. They are Toyota, Honda, and Nissan wraped in lexury and hopefully performance.
Scion however is the first factory rice car ready to mod from Toyota. Back when gas prices where really high, I acually looked at a Xa cause the Echo wasn't made anymore and I wanted something cheap. At first I just looked on scion.com. The web sight was a little anoying, but the Xa starts at $13,270 MSRP. I figured a nice stereo, a 5sp, it would work. Looking in to it some more, I learn that the 103HP 1.5L is only good for a 32/37MPG fuel economy for a 5sp.. The same car that is basicly a Echo has some pretty lousy fuel economy. Did the stereo add all that weight or what?!?!?! Well, I thought I would go to the dealer on Sunday just to see one in person. The online pics looked acceptable. The Toyota dealer only had one, but they had added so much worthless crap to it (they riced it out), that the sticker was acually close to 19K. I was so pissed. It's a good think it was Sunday cause I think I would have laughed out loud at any sales people. Now, I'm just so turned off by Scion, I'm acually just a little turned off at Toyota now.
Toyota might have wanted to spawn off a new car name and sell cars to young people, but Scion is the black sheep of the family. I only know one person who acually owned one and he had the Tc. I pretty decent looking car. I'll give it that. Anyway, he traded it in on a 06 Honda cause he said the Tc had too many strange noises in it. He wasn't happy with quality. I'm sure glad I didn't buy one. I think I would have regreted it.
As far as sales goes, I really havn't seen that many on the road. Toyota is selling them, but they didn't come up with a great car(s) that is selling really well. Only time will tell if it was worth it. It could still be a bust.
