I just bought this and drove from missouri to virginia average 25 MPG

There are bunch of small chips and scratches but some of them will go away after detailing I am sure

The guy inherited from his uncle and do not have history (I checked carfax)
But I bought for very good price it did not bother me much

I am planning to change oil, oil filter, air filter, spark plugs (not sure about this resistance no resistance stuff yet)
Is there any other things i should check, change etc.

Thanks
