Just got it about half a year ago and I think it runs great and all I have had to do is normal tune up oil,air filter, spark plugs, break pads, drums, calipers, rotors, some new fuses and I am going to get some new rugs for it but the ones in it are still good. And yes that looks like a lot but It only cost about 250 if you do it your self and go to advance auto parts and most of the parts like brake pads are life time warranty.
