Fiat Croma 1.9 Purchase advice

Hello Fiat friends, I’m thinking of buying the Fiat Series 1 1.9 Multijet 8V diesel with 120ps. The car was registered in Dec. 2008. During the test drive the Croma made a good impression. it now has almost 90tkm on the hump. I found the handling so far in order. I was enthusiastic about the space offered. In the engine room a tube of the cooling system was strongly corrided, which would of course be removed before purchase…. In the test drive the warning light was on that the security for rear window lifter does not work. Since I have already read myself bitsl through the forum, and often came across MadMax, who really caught a Monday car I wanted to listen to other reports about the Croma from 2008. Hope for a few answers, many thanks
