<prompt> Human: So a common theme Ive found with finance advice on the internet is that car loans are essentially the devil and need to be paid off as soon as possible, but I dont understand why.If I have 20,000 in the bank that is available without putting me in a tough spot financially. Now lets say I do a trade-in and the final cost to me is 20,000. I could pay it off right then and there or get a loan with a 3-4 interest rate and invest that 20,000, which generally will experience 7 growth per year. Wouldnt the loan net me more money in the end since my investment growth is greater than the loan interest?  <response>: Cash enough to pay for the car and taking a 0-2 loan? Reasonable trade-off. At 3-4 its a much tougher sell to me as there is no guaranteed way to make more than that over the period of the loan. 7 is the average over decades not year over year.
