The Makerbot scanner is indeed lower resolution, hence it's bargain price. Still, it's not useless and for a simple part might be just fine. Plus you can clean up any issues with the software after scanning. I found this to be pretty darned good considering the complexity of the figurine they scanned and printed.

I found another trove of locations that also might be nearby you for this or any future project: http://hackerspaces.org/wiki/North_Carolina

But I trust you know what you are doing, I was merely trying to provide help or alternatives.

Seeing this post reminds me that I have a new windscreen corner block sitting on my desk that Wayne sent me ages ago to 3D model and attempt to 3D print. It's a relatively simple part, doesn't need scanning or anything. The last year and a half has been crazy busy, so I haven't done it, but I will do. I can test print it here in ABS, but nylon from Shapeways is probably the best option for appearance.

I had some drawn up and printed last year but there is no option for a gloss or semi-gloss surface finish. Shapeways started off printing them in ABS but that won't stand up to heat or UV so went to Nylon (Strong and Flexible) and every way they tried, they are stair-stepped and still matte. There is no smoothing options for the nylon like using acetone to smooth the ABS parts.

DeanG got a set from me earlier this year and I think he used them when he had his windscreen replaced. I know they fit correctly but he never told me if they worked out or not.

I know you asked earlier, but I don't like what I got, so I assume nobody will like them. Maybe Dean will jump in and give his opinion.

I will take some pictures of the different versions but ALL of them are FLAT black, not semi-gloss like the side and top moldings.

Well currently I have nothing there.. just a sort of mitred joint on the top and side seals.

Is it possible they could be primed and sprayed with a satin black finish?
I'm happy to experiment and report back

No, I tried that. They are nylon and don't sand well. When you make progress, you end up with more uneven levels as they are printing "rows" side by side and they don't "blend"

I will try to get some pictures and post them.

Did you try polished nylon at Shapeways? I just had some parts done in that, it's quite smooth. Hitting it after with some paint might work out. Another option might be doing it on a SLA machine- you'll get very smooth continuous parts that could be sanded and painted.

Shapeways doesn't offer polished BLACK and the early polished white I tried was still too grainy.

I haven't tried SLA yet. Any suggestions of someone that doesn't charge high and has a minimum order requirement?

I've put a reproduction on Shapeways (http://shpws.me/MMJC). They are US$7 each plus P&P.
There's an accompanying YouTube video showing them on the car at: https://youtu.be/KXFY-cT7HfE
As John says, the finish as supplied is a slightly granular matt. If you want to match the smooth semi-gloss of the original the easiest thing would be to spray it with several coats of high build primer, sand that smooth and top coat it in a black satin. But watch the video, you may agree it looks better as supplied in matt.
Best wishes,
Toby
