I did a spit-take with a glass of rose at my lips when I saw your car. That was not a negative commentary on what you have.
In the early-to-mid 70s I was the parts manager for a dealer in Houston. As I came to understand my job and the cars, I began to detect trends. One was that the yellow spiders seemed to rust first.
I am NOT claiming that is an accurate data reduction. We were in Houston, with wet, sometimes salty air. Maybe the yellow cars were favored by people who lived closer to the coast? I recall more than one yellow car with three or four years on it than had panels flapping.
I’m actually fond of some of the Alfa yellows, and restored a yellow 2000 Touring not long ago that was a barn-find south of Houston. Least rusty 10204 I’ve ever had my hands into.
GLWS. Although I’m tempted, I’m living in the Colombian Andes and tools are still in Nevada. Not a solvable logistics problem. I’ve loaned my 77 to my nephew in Houston. If I just can’t stand it, I’ll take that running, unrestored, nice original car back. It required about $15k to bring a clean, low miles car up to regular use without need of paint, bodywork, or engine repairs.
