Jetta or Mazda?

I've narrowed down the car search to two vehicles with decent lease deals going on right now. I've test driven both twice and there are positives and negatives about both.

The decision is between:
The 2010 Mazda 3 sedan and the 2010 Jetta Limited Edition Sedan.
Both would be white or black. I've had a white car and they are easy to clean, but I love black cars because they are so sharp looking.

It's awful because:
1. I have to make monthly payments
2. My poor Explorer (Betsy) will need to be traded in and it will leave me sad.
3. My dad has to cosign with me since I have never had a credit card/ thus no credit.
4. Car insurance rates go up on a new/leased car.
5. I can't decide which one I prefer looks/feel wise because I have always driven an SUV, so these sedans are not my personality, not my style, not my anything! But they are the cheapest and most fuel efficient decent looking cars around.

It's good because:
1. I will be saving money on gas.
2. I will have maintenance taken care of.
3. I have the option to buy at the end of the lease.
4. If I buy I will end up paying less than I would have had I purchased the car with a car loan since there is no interest, I am only paying the depreciation on the car.
5. I will no longer have to walk to school/ lose hours at work.

Ultimately the price has to be right... But anyone have any votes?
