Car Maintenance

Should I be doing the car maintenance the dealership suggests?
I have VW Jetta (2006) and it’s almost at 50,000 miles. The dealership gave me a maintenance schedule with a LONG list of items that needed to be done once it’s reached 50K. It’s around $500+ for all the items. Is everything on the list necessary?
To be honest if you have the money to do it then go ahead. But they only say that so you give them profit. Plus dealers enjoy ripping people off. They do a good job but its to pricey. You can go to sears or your local auto shop to get it fixed for cheaper. Don’t go somewhere real cheap or like a very poor type place. Those people end up fixing it but purposely break something else so they can take advantage of you and make you pay them more.
