My dream car was/is a GMC Typhoon. I always wanted one and I wanted it black and one of a couple certain production numbers.
Here is my 1992 GMC Typhoon #0013 and I am resurrecting (engine was knocking and needs some paint and also gotta get rid of the horrible tail lights). Currently having an engine built for it. Then I gotta work on a transmission swap and beef up the axles a bit.
Big fan of the Mustang 1967 GT500 (especially the 'Supersnake' edition) basically 'Eleanor' from Gone in 60 Seconds and I can gladly say I own 'Ellie' on GTA:O. But there are some real good suggestions in this thread.
I currently have 1 of the 3 cars I'm realistically working towards. First is my '79 El Camino.
The second is one I'm currently working on. I live in the midwest with more snow than we know what to do with so I'm in the middle of building a car that can take me and my bikes out no matter the weather. Only thing I have left to do is trailing arm bracket spacers to recenter the rear axle. '02 Subaru Impreza 2.5TS
And I suppose I'll post the car I want but can never have. The Ford Falcon XR8. It's an Australian Exclusive that was discontinued in 2016. I admire the sleek 4-door with a honkin' V8 in it. I could have my fun while maintaining the "practicality" stance of owning it.
