Ron (the owner) quoted me $1050 (4 hours labor plus over $500 for parts) to change the alternator and battery in my '04 Chevy Tracker, stating they were "notorious" for being difficult to work on, and that they'd spent an hour diagnosing the problem and "researching" the vehicles TSB's. I already had given them the diagnosis, and it takes less than 15 minutes to pull up ALL the TSB's issued for the vehicle. Ron tried to tell me there was a lot of rust, and it was doubtful they could do the job in the "book time". They also wanted to charge me almost 50% more for the parts than I would pay for them at ANY auto parts store. I declined and did it myself after work, in my drive way, in the dark and cold with just a work light and hand tools, in 2 hours flat. Total cost? $316.00. Bob & Sons Automotive is a RIP OFF!!! Go somewhere else to have your vehicles serviced if you cannot do the work yourself.
