Potential ZR-1 Owner

[vetteguy48]

Good Morning. I have owned vettes for many years and currently have a 82CE and 19 GS convert. Have never owned a Z but have lusted after them for years. I am actually a big fan of C4's which sadly are under appreciated. I have had many over the years. I have found a 90 ZR-1 near me with vin:
1G1YZ23J5L5802178. the car is one owner with 10,500 miles. I have perused the site and already found a lot of useful info..things to look out for. I guess my biggest concern is how much time this car has potentially sat. i am going to take my first look at the car today. Anyway..any advice or consul would be really appreciated.
