My vehicle doesn't really count by the OP's standards, as the lower intake manifold gaskets have been replaced (and that will be the case on pretty much ANY high mileage GM 3100 or 3400). But my 2001 Chevy Lumina has about 227,000 miles on it. I bought it in 2006 at 159,000 miles. Put a set of intake gaskets in it and a trans. output shaft seal when I bought it. Since then, I've also replaced an oxygen sensor and a blinker switch. Also replaced an a/c condenser that still worked but was all beat up from road debris bouncing up. Everything else has been maintenance or my own modifications.
