I had to have my head gasket replaced (common problem with the 1.8L of our vintage) -- along with the water pump, spark plugs, all belts & hoses, thermostat, etc. I hope to get another 135k out of it and I am handing it down to my son in about a year and a half when he begins driving {Gasp!}.
It was repainted last spring and I had four new struts installed. My next thing is doing something about the wheels. I'll either get them powder-coated or spray paint them flat black. I just cannot ever get them to look "clean" at all, no matter what I use on them.
I get "average" mileage of about 30 mpg with fairly spirited driving. I have gotten 37 on a trip (65 to 75 mph constant) and the worst I have seen as 26 or 27 in a lot of city driving. Compared to my extended-cab, long-bed 2004 Silverado with a 5.3L V8, the Sentra is downright thrifty!! {Typically, the Sentra is my commuter car and the Silverado is my weekend toy.}
Glad to know you got 192k out of it so far. Any head gasket trouble?
