If I was going to go for the Audi. I would only do so if my DD was was not very far, and that I would have enough money in the bank for repairs.
Audi had problems in those years like VW, and while the majority were fine. You wouldn't want to get stuck with the lemon of the bunch.
So its really up to him. For me you have to love what you drive. I always have bought, and modified cars I wanted from ones I could afford.
For me I would really like the Fusion. It has really gotten great looking, and if done up will be unique out there.
