Brian,

I did a couple relatively extensive write-ups on the 107. Below is an excerpt with edits...

"Here's a list common replacement items:

- Since these cars are far from lightweight all suspension pieces suffer after so many years. Especially if sitting unused. So if not replaced RECENTLY figure on Shocks (Bilstein), Subframe bushings, ball joints, springs...etc.

- Fuel injection system on 81 and up...it's the wonderful Bosch CIS system. Not unlike the 911 you will have cold/warm/hot start problems. As usual many throw thousands chasing idle, start and missing problems.

- Climate control - This has to be the most unneccessarily complicated system I've ever seen in my life. And they will all develop problems. It is absolutely unintuitive as well. To make it more fun it's all vacuum operated with vacuum actuators buried behind the dash. They can be rebuilt inexpensively but getting to them and getting to the right one is the challenge. (This may be less complex on the 560)

- Heat: if one loses heat the faulty monovalve is a common cause. Luckily it's inexpensive and quikly replaced.

- Rust - Not the worst cars regarding this. However, the older you get the more prone you are to suffering.

- Convertible top...Very simple mechanical setup. I like it. Hard top same thing...well done.

- Interior....Dash cracks can be a problem. Seems blue cracks the most.

- Radiators also have issues, especially with a plastic filler neck. Once they break it's almost impossible to repair and not cheap to replace.

- Radio...by Becker. I'll say no more.

- ADD: The steering will likely become vague with up to 3" play on either side of center sometime during a 107s lifetime. This can be remedied by adjusting the tension on the steering (gear) box. If the box is too far gone the amount of adjustment needed will bind the gears. In that case an expensive replacement will be required. Rebuilds are available but still in the $300-$400 range and a few hours of labor in a tight area."

I've deleted other issues that wouldn't apply to the 560. A well maintained example is paramount for top dollar. Sounds like your mom's car is in that league.

BTW, Island911 was looking for a 107 a while back. Perhaps he still is. Good luck.
