Haha, why thank you! I try my best to attain all the information of the things I love and share it with others to expand that knowledge.
You can get a decent 2006 or maybe even a clean 2007 model 1.0L B or X Package. Go through the used car section, you will find plenty, but remember getting a really good and clean domestically driven car is hard. Best of luck!
Well, I like I wrote before. I won't recommend it unless you want to keep the car for quite a while.
Expense won't be much. You can get an entire 2SZ with gearbox for around 70-80K. But you will be paid peanuts for your 1KR, because that is just how it goes. Other than the cost of the engine you'll have to pay for labor.
