i know how you feel. i had a completely stock '91 GS that started having problems about 3 months after i bought it. i replaced the battery, tie rods, shocks, struts, muffler, brakes, tires, transmission, water pump, timing belt, power steering belt, thermostat, radiator, it drank about 1 quart of oil a week and smoked like no other on cold starts, and last but not least the engine needed rebuilt twice but i sold it before the second rebuild. that was all within a year. i wasnt going to dump any more money into it and for the amount of money i put into that thing, it was almost a new car minus the engine. haha. i miss it oddly enough (had immaculate interior and body) even though im still paying on a loan for the first rebuild. it never left me sit EVER...even when she decided to run on 3 cylinders, we still got home. slowly.
i think everyone has one of those cars sometime in our lives. it makes you appreciate your next car even more.
