That's awesome man. Can't take it with you so drive the he'll out of them while you can! I had an all original low mile gn back in 91. Drove the he'll out of it every chance I got and still do Now she has 77k on the clock. No regrets! No garage or trailer queens in my toy box.
Do some fog up and stay fogged up ? Mine sometimes fogs up just when I first start it and maybe the first ten minutes of driving , then goes away nice and clean . However , my boost gauge was cloudy ( dirty) behind the lens when I got it , I carefully took it out , uncrimped the bezel to take the glass off and clean it , put it carefully back together , and like new it looks !!!!!
