So, I got an '06 Honda back in.....well, '06

The only problem I've ever had with it is the battery died. I have the 36,000 mile warranty and i have about 28 miles left until I reach that. I didn't get my 30,000 mile "check-up" because I think it's sort of stupid. Why pay so much for a car and then have to pay 600-700 dollars on maintanence. Anyway, I get my car maintanenced.....oil changed, air filter changed, tires balanced and rotated. Is it REALLY necessary to get those check ups?
