Re: Retirement account and buying car
In my opinion 401K is not allowed and my source is not very strong on this so don't take my words but I would like to give my opinon.
About car I think its better to lease instead of buying on payment because that is for sure involves interest. Infect when you go buy the car they tell you how much interest they are going to charge (APR) unless if they are giving it for 0% APR.
Goodluck.
