I was thinking the same thing. I never beat mine and always ran the "tranny cocktail" and still had bad synchros on 2nd and 3rd by 80k miles. Bought it with 20k miles but I doubt the previous owner hurt it much since the car shifted great right up until it didn't
I have had many manual tranny cars and never experienced synchro issues like this.
Interesting that you've never had the UIM/LIM off...
