Nothing personal, DC, but that sounds a bit far fetched to me. It takes you 1 year to think about $50K Hummer and search for discount, now you gonna buy a $100K Cayenne just like that? somehow the math and logic just don't add up, very fuzzy indeed. Not just $50K or $100K or your tax numbers, the whole picture is out of focus.
If money does grow on your tree, then you could've bought a Hummer last year, play with it get the tax credit, dump it and buy a new Cayenne, play with it take the tax credit and move on to next new love. You need to make very good money to be able to use tax credit that size, and it takes some guts and risk to use the full credit, plus tax credit is much over-rated. Anyway, at least you have a good head to pick a nice Porsche SUV.
