Yes, I did it, too.
Since today i´m proud owner of a 1990 Chevrolet Beretta GTZ! I was very sceptical, because the car has already 90000miles on it and the owner did some ugly/strange mods to it, but the engine runs strong and is nevertheless well serviced. That little engine is really incredible!!
The 120mph speedo is definitily sized a bit too small... the needle hit the bottom of the instrument cluster often heavily.
The stock suspension is surprisingly also very good.
Nice winter- and commuter car, and sad but true: it has even more horses than my bird
But hopefully I´m soon going to change that. (NO I don´t want to slow down the GTZ!!)
RAM, are you ready to race!?! 
But I have to warn you, that GTZ has already lots of power mods!
<RICE MODE ON>
stock engine output: 184hp
cone air filter: 20hp
louder muffler: 30hp
bigger exhaust tip: 10hp
bigger shopping kart wing: 25hp
bigger fog lamps: 20hp
aluminium fuel door sticker: 10hp
chevrolet sticker on the fender: 10hp
10 small rivet stickers on the door: 10hp
Airbrush grafic of a topless amazon
who huges a beefy man (hood): 66hp
-----------------------------------------------
total power output: 385hp
Next mods are of course: NAAAAAAWS (200hp, no system, just a sticker), underbody neons (50hp) and a big windshield banner (something with "Autobahn", "Motorsports", "Tuning" or "Power" in it - approx. up to 100hp depending on the word/sentence).
And when I have those mods i´m going to challenge and beat all those slow LT1s and LS1s!!
Perhaps I´ll change even my name to Chris Diesel and start hijacking trucks. Not sure about that, though.
So RAM, what have YOU got?
<RICE MODE OFF>
To be serious: Tomorrow I´ll start undoing most of those tasteless modifications from the previous owner and bring that car more nearer
to stock condition... well, but perhaps I keep that airbrush graphic...
