Don't feel bad.

I put myself on a deadline last fall to at least get my car running good enough to take my 11 year old daughter for a ride around the block, I promised her.
I got it running just good enough to take her for that ride, with no interior in the car...just 2 seats, then back in the garage for more work.

You are on a pretty aggressive pace and that gets expensive fast.

My car sat for 10 years while I collected the big parts.
When it was time to install the drivetrain it was unbelievable how much little nickel and dime parts cost $$$$$.
I also had to back off as my toy budget was empty.

I've been tinkering with it all summer and it's still NOT completely done, probably never will be.

I'm currently battling with a creeky over center clutch pedal spring...what a joy that was to get out.

Keep your spirits up and don't try to do it all at one time..
