Bought my early 260Z in 1980 for $2500 (the sticker $2900) Immediately put $2000 (1980 dollars) in it with 4 bl Holley/manifold), suspension, radio, and assorted. Took it to Turbo Tom a couple of times and spent $10K-12K in '90's dollars and now different turbo, Mega-squirt, etc by slow_old_car and friends for approx. total of $18K-$20K. But, I didn't keep good records. Better that way.
