Well, I got my first Z as my first car back when I was 16. Cost me 2250. Over the 2 years I had that Z i got two new tires, new radiator, new carpet, tint, and power locks...so about an easy 1000 on that Z.
I had two more cars in between my first 77 and my current 78 which were a 88 supra turbo and a 95 Infiniti J30. Wasted a TON of money on the supra. Like STUPID crazy. 650 exhaust, 400 rack, 250 tint, 250 Infinity speakers, interior parts...yadda yadda. Thought the supra was going to be THE car but it just need to much to keep it going. Beautiful car though. One owner, 153k original miles. Great car. LOVED the engine....hated working on it but LOVED the engine lol.
My current Z was bought for 3150 but needed tires straight off the bat. So 3500 and two tanks of gas to drive it home lol. It needed a dash cover so I got a soft cover which was like 40. I have since bought some wheels which were 100 and then 100 to mount and balance them, new rotors up front(can't remember how much that was...maybe 300?), bought some twice pipes which were 350 installed, and then some fusible link covers. Other than that, I haven't touched it I really need to get it claybarred as the roof is starting to get really dull and am saving for wheels, struts, and some springs. Oh, and BUSHINGS! I need those too lol. So, I've got an easy 2k to save up. After THAT who knows...I will eventually go turbo but not till after college when I can get another dd and work on this one for awhile.
