New to this board. Not sure if I am posting in the correct category. Sorry for repetition, but need help! I have the opportunity to purchase a 1990 Legacy for $900, but the only thing that it needs is a water pump. I would like to replace it myself. Does anyone know what is involved or how difficult it would be? Also, I am interested to know if $900 is a fair price for this car - very clean inside and out, 109,000 miles. Any input would be appreciated. Thanks
