Nice
I had a black 1996 C4
If you look in the car for the RPO codes this is off my website for the decodes

Some detail from my website:
1996 was the first year all Corvettes had to meet the USA's smog rules and comply with the OBD-II standards
- ·A new version of Chevy's 350-cubic-inch small block, RPO LT4, became optional exclusively with 1996 Corvettes. Rated at 330-horsepower, 30 more than the base LTl, the LT4 had higher compression (10.8:1 vs 10.4:1), new aluminum head design, Crane roller rocker arms, revised camshaft profile, and other major and minor tweaks. The LT4's redine increased to 6300 rpm (5700 rpm for LT1), so LT4-equipped models had 8000 rpm tachometers instead of the base 6000 rpm. LT4 was available with all Corvette models, but only with manual transmissions.
- ·LTl engines were mated only to automatic transmissions which had improved friction materials for the intermediate clutch and front/rear bands, improved shift quality and more durable torque converters.
- ·"Grand Sport" (RPO Z16) included the LT4 engine, distinctive Admiral Blue paint with white center stripe, and special detailing. The previous year's ZR-l style five-spoke 17" wheels were used, but painted black. Like the ZR-l, tires for Grand Sport coupes were P275/4OZRl 7 front and P31 5?3SZRl 7 rear. But Grand Sport coupes had rear fender flares rather than the ZR-l's wider rear panels. Convertible Grand Sport tires were P255145ZR17 front, P285140ZR17 rear, with no fender flares. Interior choices were limited to black, or a red-black combination. Corvettes with the Grand Sport option had separate serial number sequences.
- ·LT1 and LT4 engines had a new throttle body for 1996. Those for LT4 engines had red "Grand Sport" lettering, regardless of the application.
- ·"Collector Edition: (RPO Z 15) included Sebring Silver paint and special trim. ZR-1 style 17" five-spoke wheels were used, but painted silver with P255/45ZR1 7 front and P285/4OZRl 7 rear tires. Black, red, or gray interiors were available, but soft top color choices was limited to black.
- ·RPO F45, Selective Real Time Damping, was priced the same ($1,695) as 1995's FX3 Selective Ride option, but was substantially different. Using data from wheel travel sensors and the Powertrain Control Module, a controller calculated the damping mode that would provide optimum control via special shock absorbers. It could alter each shock individually (unlike the earlier system which changed all shocks simultaneously) every 10 to 15 milliseconds, or about every foot of roadway traveling at 60 mph.
- ·Performance Handling Package (RPO Z51) previously optional from 1984 thru 1988, returned in 1996 with different content but similar intent. It included Bustein shock absorbers with stiffer springs and thicker stabilizer bars. If ordered with an automatic transmission, a 3.07:1 axle was required. Tires were P275/40ZR17 on 17x9.5" aluminum wheels, except for Z51 Grand Sports which had P31 5/3SZR1 7 rear tires on I 7x11" wheels. Z51 was limited to Coupes.
- ·1996's On-Board-Diagnostics were much more sophisticated and complex, the number of diagnostic codes increasing from 60 to 140.
If you take the license plate off, you might see on top of the gas tank the original copy of the window sticker
If not there, it could be rolled up and stuck into the front bumper frame on the right corner
