Should I purchase a used 2001 C320?

[newjuicer]

I was thinking about purchasing a used 2001 C320. The car is listed as follows:

*) 1 owner, clean CarFax
*) 74K miles (less than average)
*) Clean interior/exterior...midnight blue/tan
*) Ask price @ 12K USD

?) What type of mileage can I expect from a C320 as long as its taken care fo correctly?
?) Is this car up for major maintenance at this mileage?
?) How reliable are these cars?
?) Anything else I should look for or ask about?

Thanks in advance for any help/suggestions...
