A new car for larger family

I am a single mom of 2 wonderful kids.
A boy (born 2008) is an avid football player and needs to travel all over country to play. I do horse riding and carry a lot of equestrian equipment in my car as well as travel to meet my clients.

Just 4 months ago we've had a surprise addition to our family - a lovely baby girl. My divorce is settled and the car goes to my ex. With all the stuff we have to carry, the only suitable option is a jeep.

Considering the climate and roads in the place we live, Volvo XC90 or Volkswagen Touareg are the best options (not the latest model, of course). It will allow us to be comfortable enough and will provide much neede safety on the road. They are also approximately the same price.

I have some amount saved and my job provides a normal living, but with two kids the money is always needed elsewhere. I can't afford a new car and can't afford to pay insane loan fees.
Without a car I can't reach some of my clients, as well as travel as much with the baby. If I can't travel, the money is reduced (I am self-employed freelancer and get paid for the job done).

All your help is greatly appreciated and thank you for understanding!
