I get that you paid a lot of money for the truck but that can be fixed really easily with a silver sharpie marker. If you are married then good luck proving that your wedding ring did not cause it.
Your could have done worse...but also a better. If your not totally set on credit unions then take a look at online banks that do refi loans. Bankrate.com can also help. Also considering waiting until after the election to see of rates change.

Well that sucks. Your original question was confusing since it was asked in way that seemed like you were having an issue and did not know the problem rather than asking if anyone else has had a system failure.
Well it wouldn't be the first time that Toyota had incorrect info on their website. That Roush part is interesting. Possible that the parts will be made under the Roush brand and not the Roush Performance brand.
I dont work for free buddy....go do your own research. But I will give you a small tip on where to start....go find this guy and let him know the truck he bought does not really exist.
