depends on what you want. But lets look at numbers. If you keep the SS you will have 58-60 grand into your current car. Now if you go for a ZL1 your probably right on a 30k trade. It all depends though on if your current car is paid off. If its paid off then you spend 42 on it and will get 30 back and have to put twenty down. So in a sense you then spent 64 grand on your new Zl1.
