Yes I did a search, and even read a few hundred of the latest 1024 results.

BUT, I could not find any info specific for the 4000 series.

Are their any known issues (such as with the first few hundred made) for this run of cars that I should be aware of?

Does anyone else have a 4xxx VIN number with more than 5k miles on it? How's it going?

 

I have # 104498--red track. I have not had any problems with the car--none of the problems posted by others.
The transmission is smooth with no glitches/grinding.
My seat has that 'click' movement--I hate it but ZPilott posted a fix. I had an upholstery shop add additional padding on the side bolsters for better fit.
The tires don't have much grip for autocross but otherwise are ok.
I just installed a grounding kit, and it makes a noticeable difference.
My windows don't have grease when I roll them up. I don't have any rattles.

 

Bose in the mid to low 4000.

Other than that just minor rattle that can be fix.
