HELP, what to do?!?!

Hello dear mondeo freaks so I have the following problem and I can’t decide. my car has broken, gear damage on a golf 4 bj:2000 with almost 100000KM. The whole thing happened to me on vacation and then had to get a rental car through the adac. This was a Ford Mondeo Kombi BJ 2005. GhiaX equipment, as far as I know. I had to drive a distance of 1000 KM and I really have to say, I was very VERY satisfied with the car running nicely quiet, had durc The 2.0 TDCI with 131 hp was also great! So now I have looked around and seen that you can get the mondeos quite cheap. The qual of the choice: – I am 20 years old, but still find so en combi fine I have to choose between a Golf V 2.0 TDI with 140 ps with comfortline equipment BJ 7/2004 and 40 tkm on the clock for 1500€ or stop a Mindeo Ghia with 2.0 TDI BJ 6/2005 with 20 tkm for 16200€. I can’t get decide what I should do. are there any diseases with this model? due to motor problems etc? thanks already in advance. and is such a mondeo full cascade insured with the alliance with 40% very expensive in the insurance?!
