Believe the two biggest improvement on making the Gen V a better daily driver are the integrated backup camera/GPS system. Seeing through those rear windows while sitting so low makes backing up an anxious time.
Being able to adjust the seat forward and back, up and down with the push of a button can make for better visability as well as allowing different drivers to share the same car.
Other daily driver improvements include better clutch take up, easier shifting and better throttle response. All signicantly better in the Gen V. It also seems to pull away smoother, and has a wider engine sweet spot to reduce shifting. Better automatic temperature control, more effective air conditioning, quieter interior (GTS), improved stereo. All these things add up to better day to day comfort and drivability.
I purchase my first Viper Coupe in 96, essentially because it was everything I had wanted in a Shelby Cobra, but with additional creature comforts. It was a race car for the street, but you could also comfortably drive it to and from the track, not needing to trailer it everywhere.
Loved the idea that it had a warranty as well as an extensive dealership network. I have even had my Viper serviced at a Jeep/Chrysler dealership when on the road. Their diagnostics worked perfect, and they were able to get me back on the road right away.
Deciding if it is an acceptable daily driver depends as much upon the owner as the vehicle.
I have friends that use their Harleys as daily drivers. They would be amused that this discussion even takes place.
