Alfa GTV 3.0 V6 24V Recommendation

Hello dear Alfa driver, have seen at a dealer a GTV 3.0 with 220hp, beautiful, with 4 tube Ragazzon exhaust, leather 108tkm, very well maintained and maintained. Timing belts have already been made. The car is supposed to cost just 650€, which is very cheap for this performance. It is Built 99 and 2nd hand But somehow everyone advises me from Alfa, all say, shit, fingers off, there are always the engines broken and and and, but of the people does not have an Alfa, everyone has heard this only once somewhere:-) On the net it says that the 3.0 should be very robust and good, what is important because I drive 2000KM a month. Is it true that the car is really very maintenance-intensive and that when something comes up, it is very expensive? Does it come from that the car is so cheap??? The money is not the problem, just doesn’t want to invest hundreds of euros in any defects every month. How is the feeling in this car?
