Congrats looks like a nice car. Two things to save you some grief. I have had about 400 Caprice cop cars over the years the Cadillac is a trimmed up Caprice. That said Check the water pump for ANY sign of leakage when it goes it leaks on the Opti Spark distrib. and takes it out too a costly part. Second is these cars are now famous for cockeyed windows due to roller/slider failure in the regulators. The prevention is take a few hours pull the door panels get a can or two of white spray grease and lube ALL of the sliders liberally (the ones on the window and the ones on the inner door) run the window up and down and do it again. Do this and you will not have the roller failure. I have a 96 Commercial Glass six door it arrived with the left rear door at half mast and a shattered roller. I can't tell you how many we replaced for the cops before the Crown Vic took over. Good Luck with the car Pete
There's a total flashback to my days of owning an Impala SS. The window roller debacle caused many people a headache, if I remember right, fixing it as a preventative measure was much easier than fixing it after it was broken, primarily because you could still move the window when it wasn't broken.
Yes, Optispark=expensive. If you intend to keep it, replacing the water pump with aftermarket might be cheap insurance.
Also, I don't remember if it was Impala SS specific or not, but one of the bezels that went around the window control switches on mine got wet from some rain at a drive thru, and the water literally melted the plastic and ruined it. I couldn't tell you why, made no sense at all, but it happened, and finding a matching one was nearly impossible. Mine was black, and I had to get a wood grain one and paint it.
That was my favorite car of all, and I don't miss it a bit. Call it a love-hate relationship. If GM could build cars with Lexus quality, they'd sell billions of them.
