TweetWow dude 24k for a Jetta! That's pretty steep! Some honest advice is first off get something almost brand new but used. New cars are a horrible investment as they immediately lose a lot of money in value the minute you drive off the lot.
Second for 24k you can pick up a whole slew of really nice, dependable, low mileage (10k miles) cars for that price or under.
Third Volkswagen gets horrible reviews from consumer reports.
Seriously you can pick up an RX8, 350Z, WRX, WRX STI, EVO 8, Volvo S40 or S60, Chrysler 300C I mean the options are endless at that pricetag! Unless it's a car you've been dying to get, I would seriously reconsider before you make an impulse buy. Go try out a few other cars and see if that Jetta is still on your mind. If it is then you know that is the right car for you.
I hope this helps bro.
