Thanks to all. The red is 519G "Light Red". Ironically, it's a bit darker than Signal Red. It's had one re-spray, but there was still a lot of original paint to be found, which helped the previous owner match the paint. Spare wheel color matches perfectly. Pierre had the car for 12 months. Metric motors did an entire rebuild for about $12K, over two years ago. Not cheap. It's a great little 230SL 4-speed. Glad to have her back!
