Comparing the 1971 to a 1998
Back when you had your 1971 it was like being the cock of the walk, yes... well that old thing had it's issue's too, but rather than compare the two by pointing out shortfalls, lets take a look at what was "Optional" back in 1971 verse's what was "Optional" in 1998 
Back in 1971 Options were plenty everything from leather/cloth to engine size and
Power Windows
Air Conditioning
Power Steering
Power Brakes
Alarm System
AM/FM Radio
AM/FM Radio Stereo
Leather Seats
All the items mentioned above are "Standard" equipment on a 1998
the actual options for a 1998 are there but not near as rudimental. Over the years the Creature Comforts became standard and performance and new technology becomes the Optional equipment.
I will say that the ride between a 1971 and the 1998 or any C5 is like night and day.. Oh it is still a Corvette but more refined, each year the marque gets better and better. I don't notice near as many rattles or air leaks in the C5 and the ride is more comfortable and you be styling in more comfort and speed..
It is all relative to how you like your ride. I prefer to drive my 1981 around town, it really sounds like a Corvette with the Flowmaster 40's and I NEVER get tired of shifting that 4-Speed
.. the 2003 is a fantastic cruiser and gets good gas mileage... best of both worlds as far as I am concerned

Enjoy your search and research on the C5, they are amazing automobiles... every generation of Corvette is a winner. I always suggest to new owners to buy the newest year Corvette you can afford. The older ones are nice but need just as much if not more maintenance as the newer ones... and as they age the parts get harder and harder to find 
Good Luck Enjoy
