I don't like the looks of the 06 (even the coupe) and love my GTS. I added lightweight 14" brakes (better than a Gen 3) and the larger rear calipers of the 2001 ABS system is great. I made certain that I had lighweight Billet wheels (better than Gen 3 and 4s). I bought a protable Nav. and Sirrius with Bluetooth stereo and upgraded all speakers (better than any stock system). My engine has 9-1 Ross pistons, 708 cam, 1.7 rockers, Roe 10# supercharger (200rwhp more than a Gen 4 and 300hp more than a Gen 3), 1,000hp rear titanium axles, Corsa track and Cat delete, Headers, custom body color valve covers, and intake tubes as well as airbox. All the junk Runcraps and even the PS1s are obsolete so I have PS2s and love them. I built unobtrusive cupholders (removable) and added a Tire Pressure Monitor System (better than any factory system. I have some other custom touches that also improve my car greatly like my SRX built in radar detector. Then I bought a Paxton supercharged 802rwhp ACR that has nearly as many modifications and drives much like a Gen 3 (smooth and pretty quiet).
If you need stock you probably need a Gen 4. If you want the best there isn't one. Someone always has faster, louder, quieter, prettier, etc.etc. I often attend car shows and like going home with 1st place and I like owning a mid to low 10 sec STREET car. Sunday I brought home the AutoX first place trophy and we invited Porsches, Mercedes, Mazdas etc. My 2001 Viper GTS took home the plastic (or bagging rights for a year Greg says). Installing a Venom spoiler to my GTS because the one on my ACR looks so good.
I like building cars and can't leave the damn things alone as I'm always improving them. Check out my ACR because maybe you want a supercharged show and go car that kicks serious asp! I think of it as buying a slightly used (26,000mi) $140,000 car for only $55K. If you buy it, you can use it to win your own trophies. Mine don't come with it
ACR, Paxton supercharged NOS = 802rwhp - ViperClub Classifieds
There's a link to the two burnouts I did with the car while testing and tuneing the car recently. Listen to the Hi-flows and Corsa exhaust! New tires, brakes, etc. On the Paxton this car has about 55 more bhp than a Gen 4. The Nitrous bottle can be left at home unless you plan to do some serious asp kickin' with 802rwhp - I never even turned it on.
To get decent power with a Gen 3 you need either a Paxton or a TT.
