Do you think mechanics work for free ? anytime you go INSIDE any car over 25 years old, you hope they can fix it for the price quoted, The Next time you call a Plumber to unclog the kitchen sink and they quote you $199 and when they leave they charge you $399 because the main line was plugged...... you may be upset but you pay because..... it's the same thing here.. At Phantom Works or Bobs Plumbing....they gave you an ESTIMATE.....right.... did they tell you to pay in advance ? ESTIMATE. I have a '97 Triple White Firebird Convertible w/38k and a '95 Triple Black T/A w/138k and every time I take them in I HOPE they come close to the ESTIMATE, when they don't it's because they are old and everything the shop touches is OLD. User's recommendation: If you don't want to take a car in for repairs buy a new car.
