Bill,
I would have few, if any, concerns for that usage with your current mileage.
Robust routine maintenance and observation are paramount, but the ZR-1 will handle that for many more years. I would expect it to easily reach 200-250 k miles with relative ease. Just scan those gauges frequently and avoid "get there - itis" if something is amiss.
The joy of driving it will be certainly well worth it.
There are some concerns however.
On a rainy day, do not roll down the window to pay a toll or at a drive through else your pants may look like you had an off - center accident.
On hot days you likely need the painted top or a liner for the transparent top in order to maintain a comfortable temperature.
Be prepared to not have a stroke when a door gets nicked or a stone chip happens.
Don't expect it to remain in concourse condition absent hours each weekend cleaning it back up.
Allow extra commute time. This will accommodate the frequent admiring car nuts enough time to gaze at your car and ask you questions about it.
EVERYONE will want to challenge you at a stop light. Discipline may enable you to keep your drivers license.
You will leave for work early each day for the fun drive, as well as leaving early for the return trip for the same reason. You may seek out longer routes as time goes by.
Most all Corvettes and collectables age far better with regular usage as opposed to spending time under cover. That usually far offsets the usage induced needs.
Many collectable owners who see you driving the ZR-1 in that fashion may find themselves dreaming and ultimately doing the same.
In summary; Go for it and have FUN!
