My car runs fine, and I don't think I need a new one. However, it's 10 years old and has 137k miles, so I'll need a new one in 2 or 3 years. But I was thinking, with interests rates being so low, like close to zero in some car ads, maybe it would be financially advantagous to replace it now if I can do so at a stupid-cheap interest rate. If I wait, I probably won't save up all the cash needed at the time of purchase, so the $$ difference looks fuzzy to me. Thoughts?
