I just went sort of through the same process you did. I am not sure how much money you are pulling in and how nice of a house you want but...
I just took my job with cummins and the pay is great. I made a budget on excell to see how much house/car payment i could afford.
First things first...make sure you buy your house first. A house is an investment, I would hate to see you not get approved because you bought a car.
I bought my house and my car a few days after, when i got my loan for the car, the loan i signed on my house still hadn't showed on my credit.
Houses have a lot of xtra expenses with them, especially right after the move when you get it up to snuff. example, i redid my bathroom floor because it was built with carpet (ick) i spent money on more stuff also.
If i could do it again I would wait a few months to get the car, just to wait and see how my expenses level off. Might be easier for you to do since you aren't moving out of state but none the less make sure your car payment isn't too much and that you can still have money to go out and also money to save.
I opted for buying a cheaper NEW daily driver. the 06 civic is plenty of luxury for daily driving and i got to keep my RX. I was seriously considering 350z's and 3 series but the whole idea of now knowing how a car was treated in prevoius hands turned me off. also, 41 mpg on 87 octane with the A/C on is really nice. specially if you have another car that is your fuel hog.
I am not telling you to consider a slow daily driver like the civic. but I am just giving advice since I just went through the process
if you have any questions let me know
