Changing an altenator on 2002 Millenia S
 

Hello all! I have a '02 Millenia Sand was quoted $550 toreplace the altenator. Ithas 62K miles and was wondering what else, if anything, should be replaced or checked while manyparts are removed (being it is quite spendy to change the simplest things like spark plugs)? I bought the car in Sept. '06 and do not know of any past work/maintenence under the hood. Any help on this would be wonderful! Thanks!
