All systems function normally or are in excellent condition.   Engine runs smoothly and strongly. no knock. smoke or oil eating (PO did a top end rebuild at ~40k miles).   Compression is 125-120-125-117-120-120* (just checked).   For a video of the running engine. go to this URL:   http://youtu. be/G7IY3YNxRe4
The Quantum Mechanics-built transmission/overdrive (on steering stalk) performs magnificently. and gives the car great jump with the 3. 89 diff while still able to cruise with the OD (speedo is non-OD original).   All suspension. brake and other drivetrain components are in like-new or excellent condition.   Most of the rubber on the car has been replaced. including front and rear windshield seals; tires are like new.   Oil has been changed every 3k miles or less.   There is no power brake servo on the car; was hoping to install it but ran out of time.   One part of the driver's side floorpan has long ago been repaired (like this since I owned the car); there are also non-structural rust perforations on the bottom of the front bumper support rails.   There's a scratch on the passenger window and evidence on minor rust under the paint inside the front fender lip (photo).

There is nothing on this car I haven't maintained or inspected; e. g. . every major bolt has been reinstalled with anti-seize. as I intended to keep the car forever.   It's been fun to own and gets a 'thumbs up' everywhere it goes.   Car is located in Arlington. Virginia.
