Their copies of a Centra wheel. I got them from a member on here when he upgraded his wheels.
Funny story. The UPS guy who comes to my work sold me a set of wheels that looked like mine after seeing my car. they were the real Centra wheels. I passed them along to a friend with a W123, they look really sharp on his car.
The roof rack is a Yakima. I keep an eye out at the junk yard. so far I have a set of bars for the SD, 4 bars on my Tercel. I have a roof basket, the bike attachements and the ski/snow board attachements. They are kind of expencive new, but can be had cheap on craigslist, and even cheaper at the junk yard... oh, you might notice the bars on my rack are yellow, thats because when you get the racks at the junkyard they can be pretty rusty, but 3/4" coated ridged steel pipe is the same outer diameter as the Yakima bars with twice the wall thickness. you can get the pipe at any hardware store, its for buried gas line.
