C240 2001 routine service

We have only 25000 miles about 5000mi per year.  I have been using an
independent shop which charges a little over $500 for an A service.
They do only MB, BMW, and Volvo and seem very competent.    I was
considering the once a year stuff like oil and filter once a year at
5,000 mile and a complete A service every 2 years at 10,000 miles. 
Anyone see a problem with that??
