The L98 is an OK engine but under-powered, Good luck finding someone to work on pre OBD 2 vehicle.....Better to find a GM specialist to work on it!! Not that they're special or overly complicated, I've just seen too many C4's get hacked up by ignorant mechanics.
OEM-NOS parts are starting to dry up & prices are reflecting it. These cars did not age well & even though your contemplating a low mileage example.....It's still approaching 30 years of age. Start using as a car instead of a garage queen.....You'll quickly find out what I'm speaking of.
If you like them, That's all that really matters!! Just keep in mind the honeymoon phase ends quickly & the car "feels" quicker than it really is.....For example, A L98 Corvette has about the same acceleration performance as a newer 2GR-FE Camry.
I'm not a C4 hater, I just want you to go into this with both eyes open!
No...it is because the C3 was, at the end of its run, a twenty year old design. (The chassis carried over from the 1962-vintage C2.)
The Tuned Port engines are actually quite easy to service (no tools beyond a jumper wire needed to pull codes), with an enormous amount of information online about them.
My biggest worry would be the early TH700 or the weird Doug Nash 4+3 manual gearbox.
