This is my first post here so please bear with me...
I am newly posted to Germany (July this year), and need some BMW advice... I am presently driving a 325i, but this is only my starter car (dont get me wrong, it blows my old car away, even though it is an 89...

What I want though, is a Cabrio, and to avoid paying duties and making expensive modifications to the car when I return, it must be a 92 or older (15 years old when I go back). When looking at one of these cars, what should I be looking for, and what should I watch out for? The last thing I want is to end up with a lemon, and 85 to 92 Cabrios are so common here, I dont know where to start... Any advice, recommendations on pricing, or helpful web links you can give me would be much appreciated.
Cheers...
