Yeah. I'm thinking that if I can find one for a reasonable price in good condition I will go for it. However, I was kind of thinking of spending my money on a 4 banger, for gas mileage reasons...when the '76 is dont it will be like 6 mpg in town
Nooooooooo no no no no. If I was gonna get a fun speed car I'd get a 5.0 Mustang with a stick. Or an old Z-28 with a stick. 80's pony cars are fun to drive and you won't feel bad scuffing one. I came close to buying a realy cosmetically shitty looking 5.0 Mustang with a stick just to have fun with. The car has 130k and was like $300. I shoulda got it.
YOu could hop up a GN to be a GNx killer for so much less than a real GNX. You could also do the same with a T-Type. I'd take anyone of the three as long as it was a solid roof car. No t-tops, sunroof.
I've seen GNs have an ask as low as 8K but that isn't going to be the best car. Browsing in the local autotrader in my area indicates 12K buys a nice one. If you can "settle" look for a 86-87 T-Type. The later cars got the intercooler. Buick made the turbo Regal between 78-87 and there are actually a lot out there. There is a Type with a solid roof for sale by my house.
As to the question of a GNX kit containing fender flares, heat extractors (probably decorations with a kit) and emblems, I've never heard of such a kit but that doesn't mean it is not out there. More went in to a GNX than that though. A T-Type with a bigger turbo, intercooler, injectors, tuning, etc would run you a lot less and be just as fast if not faster. The Buick T-Type is a nice option. If you get one, do what The Stones sang - "Paint It Black"!
See, all it takes are some late 80's-90's Trans Am wheels to get closer to the GNX look! The T-Type for sale around here had those but the guy put the factory T-Type wheels back on it. It didn't help the curb appeal if you ask me.
Mine has Draglites on it, but I still have the stock wheels somewhere:
You can get 20 MPG out of the V6 if you keep your foot out of the turbo.
They only made 547 GNXs so they're going to be REALLY expensive. And if you buy one the only way to maintain your investment is to keep it as a garage queen. They weren't that much faster than the GNs and by the time you apply some modern tweaks to a 'regular' GN you've blown the doors off a GNX. The engine in the GNX was the same as the GN. The turbo had a ceramic coated impeller wheel, but it was the same .60 A/R compressor wheel as the GN. It had a different chip and intercooler. The big differences were in the suspension, which helped it produce better 0-60 and 1/4-mile times.
Despite being the most 'common' of the Turbo Regals with 20,000+ produced in 1987, the '87 GN is the most expensive to buy (next to the GNX and some ultra-rare T-type cars). Your best bet is to pick up an '86 or '87 T-type. They have the same exact drivetrain as the GN but you can get them in lots of different colors and with column shifters and bench seats.
I finally talked my brother into joining the Dark Side. He sold his WS6 Trans Am and picked up a rough 1987 Turbo T. In '87 there weren't any "T-types", they were "T"s, with a 307 V8 version and a turbo version, hence the "Turbo T" designation. He hasn't had it long, but he's already running mid-12s with it. They are a blast to drive and rip up the 1/8th mile in a hurry even in stock form (which makes them stoplight terrors).
My GN is absolutely the most fun car I've owned. You definitely won't be disappointed with one of these cars.
