Since purchasing with approximately 143,000 miles, the engine has used a *lot* of oil, a quart every 670-900 miles(!) A mechanic friend suggested adding Seafoam to the engine oil, which I did for approximately 200 miles before changing the oil. We'll see if it helps.

Two (plastic!) coolant bleeder screws were broken and leaking near the supercharger. Had to be tapped out, remnants of plastic in threads removed, and new screws installed. After the repair, oil usage increased dramatically (1 qt every 200 miles or less!). Couldn't get back to shop to have them address for a few months, then went on a one-month long trip during which the car just sat. After sitting for that month, oil consumption has fallen to nearly 900 miles last time I checked. Quite bizarre!

Car was hemorrhaging coolant from a gasket under supercharger. Had intake valves cleaned while the supercharger was off.  Access plug to left headlight was missing and allowed water to get in, destroying wiring and ballast, so used headlight assembly was installed.
