Problem sorted, I managed to get her an used 1996 BMW 523i E39 from a friend, who bought himself an Passat 3c...
Anyway, it's a beauty, 2.5l 170bhp Automatic which is kinda slow , but only 95k miles and everything works. It has everything except leather seats, HID-lights, sunroof and a satnav, all for just 2000?.
For the same Money you could buy her old Audi A6 from me, 3.0l V6 5V, 220bhp auto, heated leatherseats, and and and... if you want?
That's a good choice it's a very solid car. My dad had an E39 520i and it never had any serious issues in say 170 000 km's. The only thing I can remember of was the temp gauge sensor went mad after 160 000 km's.
Edit: Oh, another one on its later days was when you drove it very fast to a bump on a gravel road it dissabled the traction control by itself. A very usefull feature. Probably a loose connection or something.
another edit: Also my uncle drove his -96 E39 523ia touring forever. I have no idea how many km's it had but probably closer to 300k. He changed it last year and believe me that would have happened a lot sooner if the car wasn't so good.
