They just sold this car on Barret Jackson for $69,000. I just watched this and had to do some research on it.

Apparently, GM stuffed a 510 c.i. big block in this thing.

...I was gonna say, before even Looking at it, "if it has the Billet Plate on the Top of the Engine, I know what one you're Talking about"...and sure enough, this is the one.

Motor Trend or Car & Driver did an Article on it YEARS ago, def. back in the 90's.

These cars handle very, very good FYI.

Some mis-information too. The car is a 4 door SEDAN, not a coupe. From the factory they have a GM 12-bolt with 3.08's and a limited slip. Not a 10bolt like stated.

My late pappy has a '96 under a cover in the garage with a factory fresh 7,xxx miles. Less than Eight thousand miles.

Yes, they DID handle very well. There's a reason why GM took the 9C1 police package and detuned it into an SS. Those things can run and handle with the best of them today.
 
All I can say is that would be a rocket ship of a ride with the bigger engine.

I know first hand what a 1995 LT1 (350) was capable of. I took that car to the limit many times and it held up like a tank and never failed. It was no ride for the faint of heart. I look back and all I can say is God was my co-pilot in that car many times. I was younger, braver and dumber during those years and I would put that car in the curves and I don't know how it stuck.
 
I think I remember that car from the mags. Wasn't that a little experiment by Ummm, I can't remember his name. He was like 6 foot 6, and wore glasses....what was that guy's name? John sumthin'... Jon Moss? He did the first Big Block Impala SS in the mid 90's. It was rumored that had GM continued that model into 1997 there would have been a manual transmission option. Very cool!

I have a '96 B4U which is the Civilian model of the SS/9C1. The springs are softer and a few other little tweaks, but the LT1 pushes my car purty quick for a 2-ton sedan. Mine has a set of Hotchkis sway bars and BMR boxed lower control arms, and it handles very well. It ain't a Corvette, but if we start tradin' paint the corvette ain't gonna like it! ):h
 
yep,there a few 6-speeds that were driving around Detroit and Arizona ,,[i drove one with 2 turbos][a callaway]
 
I'm seriously considering an Impala SS right now. Just recently saw one with a 502 crate motor, two bottles of nitrous in the trunk. Gorgeous car, scary fast and sounded absolutely amazing. So that got me on an Impala kick, but I'd obviously be looking at a stock one.
IIRC I read somewhere, wikipedia maybe, about the prototype car having a big block.

Nick, what was detuned about them? Only thing I could find different was something about the body mounts not being installed up front?
 
From a mechanical standpoint, it used the Caprice 9C1 police package as its base and got most of the equipment available only to law enforcement and government agencies. This included a sport-tuned suspension with reinforced shocks and springs, a high-capacity upgraded reverse flow cooling system, larger and more powerful four-wheel disc brakes, transmission cooler, dual exhaust, a 140 amp alternator, and other minor mechanical alterations. The Impala did not get the external oil-to-air engine oil cooler, nor were all the body mounts secured (the standard Caprice and Impala SS were assembled at the factory with the front 3 body mounts missing one of the rubber cushions, while the 9C1 was assembled with all rubber cushions in place), although both are popular aftermarket additions to the Impala SS by their owners.

The 9C1 had an external oil, tranny and power steering cooler. The SS only had the oil cooler. The SS sat 2" lower but the suspension was "softer" than the 9C1.

Some also say that the tuning was more aggressive in the 9C1's.

Impalas and 9C1's got a larger rear axle over the standard Caprice as well.

The air dams were different on the 9C1's that redirected the airflow directly to the brakes, keeping them cooler.

Its basically the same car, minus some durability options that the 9C1's got. It was way easier to clone a police package than to clone a granny package to 9C1 standards.
 
Well, right now I am struggling to decide what to buy. I am looking at a 65 Impala 2 door (one of my all time favorite cars) needs a little work but not a full resto. Looks good. Other is a 94 SS, 130k on it, couple minor imperfections but also looks good.
65 is cooler, 94 is probably a whole lot more reliable and fun to drive. The 94 is a lot closer and would be much easier to just buy and put on the road right away. I'm a little concerned about the apparent resale. Checked what's sold on ebay and values on NADA guides, they are worth a lot less than I thought. So even if I make a good deal on it, it's probably never going to be worth any more.

What should I do?
 
Wish I could, but wifes already getting tired of my crap. I have two one ton duallys that I can't quite justify needing, but I wanted another one.

I'm waiting for some pics to come in from someone selling a custom painted 95 SS. It is (you ready?) vanilla white. I can't wait to see it! It's either gonna be beautiful or hideous, I can't picture it in my head very well.

Still torn as to what to do. Lot more SS cars around than 65s.
 
What a nice car!

I have fond memories of my old Impala...damn thing would pin you to the door around a clover leaf. Handled like a slot car and way comfy on the highway.

They sure make a sharp car...:thumbsup:
 
Testing the waters here, what would a '96 SS bring with less than 6,000 miles? Garaged, covered, all OEM perfect, dark cherry metallic paint.
