Re: new boy!
You are probably being told not to buy by people that don't know Alfas. The bad reputation of the past is unwarranted, they do have some niggles but they drive beautifully and look better than anything else on the road. It depends what you want - style and excitement, go Alfa, dependability but the same as everyone else, go German. Read the forum for a bit and you will get a feel for the GT "niggles".
The biggest issue with Alfas remains the depreciation. So if you are buying new, plan on keeping the car a while. But that means if you buy seconhand you can get some real bargains.
