Replaced all 4 disc break pads & rotors. Replaced Brake fluid & bleed system. $400. I replaced the thermostat and replaced radiator-cooling fluid. I replaced the coolant expansion tank with an aluminum one as the plastic tanks are prone to abrupt failure, for an additional $230. 6 speed manual transmission shifting plate, shifting ball, turrent fluid, transmission fluid. I replaced differential oil, air filter, spark plugs. I fixed the seat belt retractors which did not retract. I sealed windshield crowl screw gaskets which were leaking water into the car. I de-clogged rear drain holes which were causing runoff water from to top to flood the interior. I replaced broken factory CD changer-stereo for an additional repair cost of $500 in parts. I also removed and lubricated squeaky anti-sway bar bushings, took about an hour and no parts. About 2 hours changing the HID lights, fog lights, licence plate lights, & side marker lights. I also bought a new fabric top, but need to wait for warmer weather to replace it. I replaced broken key FOB which will require a locksmith to program and will end up costing $400 total.
