it is better for you to learn how to take care by youself. there is no good shop take care your car cost low price. if you willing to pay big $$ any regular shop will take care of your car.
in one condition, if the car still run good, then it is worth to pay more money on it.
recently, I deal with a 94 lexus it have 200k on it. still in good shape.my friend want to keep it.so he ask me to do a real maintanence on it. he never trust any shop.
so if you in s bay area, we can do some business.
