Hyundai's are great cars. The loaded Santa Fe's are legit full luxury SUVs for 20k less than you'd get elsewhere. 12 year warranties, oil changes for 5 years, there's nothing better in terms of bang for your buck out there. I just bought my wife one and she works with people who drive Audi's and BMWs who are now looking at trading theirs in.
MadHatter is right, only concern yourself with the bottom line - price and interest rate. If you can't afford it, get less car. In general, the invoice price on a new car is roughly $1500 less than sticker on cars less than 30k. If you can get a black book you can calculate the exact invoice the dealer paid and don't pay a penny more(the dealer will still make money on kickbacks). Just stonewall them on that price and they'll eventually take it.
black book? that is for used cars my friend. Thats just a weekly guide of the auction value of each car.
