While messing around on the Paudi model website thanks to Brinkman's post, I discovered that I had one, and maybe 2 of their models. The one I'm somewhat certain of is the 2006 Toyota Crown. The reason why I didn't know it was made by Paudi is that the only english writing on the box or car is Toyota Crown and FAW Toyota Motor Sales.
As for the model itself, it's about a notch or two below a contemporary Kyosho in terms of build quality. The main issue is the alignment of the doors, though it's much more noticeable in these pictures than it is on the shelf.
The model features the standard complement of opening doors, hood and trunk, but the Chinese market models usually feature more than that. In this case that means that the fuel filler door opens, the transmission shift lever moves, the front and rear armrests open, and the sunroof shade and front seats slide back and forth. Another feature of this executive class car is the footrest in the front passenger seat: the center section folds down so the rear seat occupant can put his (or her) legs up.
Overall it's a pretty nice model and worthy of your consideration, especially if you, like me, want something beyond the usual Euro-luxury, and Sports and Exotics that tend to dominate the diecast scene. The main issue, at least from a U.S. perspective, is the non-existent distribution on these shores, meaning expensive shipping from Hong Kong or mainland China.
