Hey all, I just bought an 02 civic for economy driving and I love it. It's a sedan DX 5speed. I haven't tested the mileage yet, but I'm sure it's going to be good. What should I expect?

Also, I would like to look into adding a few things. What do i need to add cruise control? I would also like to get a new cluster with a tach. I saw the DIY already, and it looks simple enough. Are these clusters hard to find?

The car has 92k miles on it, but the plugs were changed to NGK platinums by the lot I bought it from. The timing belt and accessory belt were also replaced. What are some areas I should look at for maintenance? What are problem areas I should be aware of in the future? I know these are reliable and cheap cars to work on, but I dont want any surprises Thanks guys!!
