Is 100% Vehicle Condition Possible?

[dgh]

One of the things I started doing in my current game is to find all of the vehicles in town with 100% Glove Box, Engine, Heater and Trunk and pull them out to a separate spot.  Then those vehicles are part of my pool of top tier repair candidates.  In my quest to repair a vehicle to 100% overall condition, I have found that despite all parts being 100% the highest I can achieve is 99+% .. the latest being 99.34%

 

The first time I noticed this, I figured it was because I had repaired some bodywork to 100%..  On my most recent attempt, every part was a fresh 100%, with no repairs and the overall condition was still coming up short.  I figured maybe it needed the battery and gas tank filled to capacity, but that didn't help.

 

My last theory is that some of the parts are not actually 100% 'under the hood' so to speak, but are being rounded up for the GUI.

 

Not sure if this qualifies as a bug or if it's a deliberate design decision.  Obviously not a big deal, just an interesting quirk I noticed.  I know B41 stuff is of vanishing importance, but just in case this carries over to B42, it might be nice to have a more exact condition report.
