Buy vs Lease Scenario

The car calculator recommended that I buy instead of lease. I currently can only afford to save for what would be considered a lemon in the eyes of many. But, I have the means to put enough work into a car that may have problems. If I was to finance a car, it would help tremendously with my credit but I am not certain that, this is the route that I want to take. I have so much going on and I just want to consolidate my bills before I pile on more. Taking on more than I can handle has never been the issue but resistance has. I also want something that I can customize. I do not mean in a way to be flashy but there are certain things that I would not do unless I was certain, that I would not be making car payments for a lifetime. I cannot ride in a car without music and even though this seems like a weird reason, I need to be able to upgrade my stereo system. The recommendation was only helpful for reassurance purposes. I need something for now with a possibility to last. I find nothing wrong with buying a used car. I will follow the recommendation and continue to save for my car. I plan to buy one in January and if things keep going the way that they are, I will have my second car. Others may feel as if a used car is not worth the risk. I currently walk everywhere that I need to go but to me, the risks are minor compared to what will happen if I do not get a car. When you do not have much, how can you be expected to weigh those nonexistent options?
