Okay, I will give it a crack for you!
I have owned the same two basses (an old Yamaha BB300 that I hardly ever played, and a Carvin LB76 Fretless that saw 99% of my playing) for 10 years until pretty recently, so keep that in mind when I share my opinion of my RB Corvette $$.
I am a lefty, and the options are fairly limited when it comes to basses. I decided that I want a new fretted bass to dork around on (mainly a fretless player still), but wanted something different than a jazz-type, so I got one of these for $425 off of Fleabay new.
First impression of mine was that it seemed pretty well put together. Could set it up as low as I cared to with no buzzes, finish looks good, hardware seems fine etc. The pots/electronics seem okay, not great, but functional.
The bass sounds pretty good to me actually; Sounds similar actually to my (newish) Squier VM jazz, but a bit more "aggressive" due to the HB's. I think the series/parallel switching is pretty useless on the bass, but you do get some control of the sound in a similar fashion to a Jazz based off the V/V/T set up. I use a VT Deluxe, so I don't really care about the lack of active electronics that much. For what I paid, no complaints.
I hope all this helps a little bit; I have never played a German $$, so at least you won't have to worry about that from me!

Please let me know if you have any other specific questions that I could try to help you with.
Here are a couple glamor shots for you as well.
