I found my 2017 Chrysler 300s on the Carguru website. The listing showed that the car was at a local used car dealership. I drove the 40 miles to test drive it, and ended up driving it home that day. Next time I'm in the market for a vehicle, I'll try Carguru first.
Some differences in engineering might be attributed to the fact that some of the recent AMT kit offerings actually started life as MPC kits back in the day. I remember a few of the MPC kits were a bit fiddly.
There are some vinyl top kits available, but I can't remember who makes them. I think they come in black or white. I've used the masking tape method before. So far, it's still holding up. One problem that could pop up is sticking to the contours of the roof. Next time I try a vinyl top, I'll be using the spray paint method.
I had an aggravating experience yesterday. I was in the carport, having a battle with three or four wasp nests. I zapped the nests with spray that would shoot 20 feet. Wasps would come at me, and I shot them, too. I used up four cans before I realized that some of the wasps that zipped across my view were the floaters in my eyes!!
I tend to agree on the blue backs. They would compliment the blue rocker stripes. Of course....that's just my opinion. Everything is looking great on this build.
I recently repaired a window unit from an old built-up that had yellowed. I wet sanded the piece, using the Micro Mesh sanding cloths, the same as I would have for a paint job. It came out good, and I could see through it, again.
