If the car is paid off, sell it and buy a beater to save even more cash.
Buy a place, raise your tax exemptions and get a nice return at the end of the year. After some time, you'll be able to replace the z with something even nicer.
Just my opinion though.
I could have gotten my M3 a LOOOONG time ago, but I chose the house instead.
Just a personal choice that's all.
Now my priorities have changed and although I'm dying to buy an M3, I'd rather purchase a new entry level Lux SUV (Infinity FX45) in anticipation for a family.
That and I'm doing some remodeling to the house.
