I know nothing of fenders and mirrors or much else about the W140 since I'm only a month into figuring out mine. I can help you with the front headrests, driver's door lock rods, front seat height mechanism and AC air filters but that's about it. I've yet to change the oil in this thing. The coolant is green so that's the next job.
No way I'm going to Orlando in July. Maybe in January but that's when San Jose is at the right temperature for me.
Buy a Diesel and I'll fly out to help you sort it out
