i love my xterra its a 01 first gen with around 84 thou it runs awsomely no probs yet accelerates like nothing ive seen ive raced differnt vehicles and have won i love it wouldnt go wrong but if your concernd about problems there might be every vehicle made is differnt from all the others and could or could not have any problems, most likely not and gas millage is relly not that great and depends on driving styles
