I like to think in percentages as well, but let's all be honest with ourselves, if we were making car buying decisions based solely on economics, none of us would be on here. That said, you definitely don't want to over do it. I think it's a good idea to think about a worst case scenario - what if you lost your job, how long can you last on your savings? A year? It's also good to think about income growth, and your visibility there. If your income will remain as is for the next few years, you may want to think differently than if you expect 30% annual growth.

And for those who think young single guys making over $200k should be driving around in Lambos, that just seems a bit absurd to me.
