For daily driving you will need better tires, IE Nitto DRs, a spare tire in the trunk,and detune it for pump gas or install an alky kit((Razor/Julio's PAC kit) alkycontrol.com).
A ten sec GN usually is running a large amount of boost, combine high boost with pump gas and you get big detonation and kill the motor over time. I would get a full list of all the mods to include tranny and stall amount, then post them.
Looks like a nice car.
If you have never owned a GN before you need to do some reading and try to find some locals that can steer you in the right direction as bugs appear. These cars are 18 years old and have issues on occasion. If the previous owner was meticulous with maintaining it, knew how to tune it, and put the right combination of mods on it then you should not have many issues.
These cars are the best!!!!
You will love it.
