Hello Maui
Welcome and congrats!!
You have just landed on a fantastic website with plenty of people seriously sophisticated and informed about these cars.
Sounds like you have scored a beautiful, as new, car for yourself. One of the best ones Mercedes ever built; that were all over the place in Europe as Taxis, with diesel engines.
Parts are definately available, and probably your best best on the West Coast would be Phil at Fastlane, on the portal page, of this site, who has a great rep and is really helpful and has good prices, and if you use him, you'll be supporting the site's premier sponsor.
A good second choice might be Randy Steele at EPS parts in Santa Barbara, I had great service from him but it was quite a few years ago I last bought from him.
I wouldn't go higher than 16" wheels on these. The cars weren't engineered for them, and there is the possibility that the steering geometry could be affected in a bad way if the wheels were too big.
Tire Rack is a GREAT way to go. I just did a few months ago, after months of research about it. You will need to fine a co operative Tire Shop to work with, and you could pay them direct, and the Shop could then order them on their Tire Rack account. Tire Rack supports the site, you are helping them and the site if you use them
You will need to buy your own center caps, but those are on ebay all the time, usually
for about $25 the set. Also, you will need buy and to select wheel locks (I don't like them) or not. Tire Rack wheels usually don't come with center caps and wheel locks.
When dealing with Tire Rack try to get wheels with the proper offset thatdon't need hubcentric spacers; also, make SURE the wheels ARE in stock.
You will hate it if they aren't. I had delay after delay because I did not check. It took months; Tiore Rack has NO control over its manufacturer.
Great idea to get Euro lights. It's the first and best thing you could do for your 300E W124.
There are lots of write ups on how to do the install, and where to get the best set ups cheap. You gotta use the search function.
I'll start you out with a couple of links. BENZ-LGB is the resident expert W124 headlight install guru, and could walk you right through it. You'd love not only the look, but the wonderful beam pattern increased output and sheer pleasure of night driving with them.

You can search more for more pictures and information.
Don't forget to fill out your profile more fully, and an avatar, and signature, and mention where you are located and the cars you have. It is good manners and helps us help you, faster.
"Maui" suggests you might be in Hawaii someplace. (Maybe Maui???!!
)
Why do you want clear corners? A personal choice, but the ones the car comes with are fine.
Also, some of the aftermarket corners might be low quality, not seal correctly or not very reliable.
There used to be a Mercedes Benz advertisement which said, "Every time somebody installs an aftermarket part of a Mercedes Benz, a Mercedes engineer in Stuttgart gets a bad headache."
