Thinking about getting a W123 300-series, this would be as a daily driver. My questions are the following:

How reliable are these cars? How many miles can I expect to get out of one that has a decent maintainence record? I've read some excellent things about them, claiming "2-400,000 miles."

How much of a problem is rust? If a vehicle has some wheel-well rust, should it be avoided?

Finally, how difficult is it to obtain parts for these 20-25 year old vehicles?


Thanks
