I did the build your own a few times and I got really sick of it finally. I built a 1971 Buick Skylark SS, 1965 Impala SS, and an 1980 and 1981 Z28s. I drove the Z28s like regular cars, rolled the Skylark and finally sold the Impala. All were fun but a lot more expensive and more hastle than I would have preferred. I built a 400 cu in small block for the Impala and it was so powerful I bent the sway bar, broke the shocks and bent the drive shaft at various times. The 10 bolt was hard as nails but everything else wasn't. Should have had it reinforced but.. Anyways I don't even change my own oil anymore. I just buy something 3 years old at a good price and be done with it. Run it for 3-4 years and change. Right now I haver a 2005 black on black Passat 4-motion with high output V6 and all the bells and whistles. Had it for 4 years. It's not a new 'Cuda or 'Stang but it matches me.. lean, muscular, and a little distinguished.
Building your own can be fun but rarely do you fins someone still doing it 3 decades later. There is a really nice 69 Chevelle in my parking lot though.. very sweet ride. Would love to take it for a spin.
