It's time for a divorce.....
I think its time for a divorce. At the rate of $100.00 a month, it would take you about 10 years to get that car up and going. There is an old saying in the USA . "It's ok for someone to look at your wife, but it's not ok to let someone drive her all night to Moscow".
But seriously, your best bet is to get ALL your parts right here at this website, it's called Fastlane.
Good Luck, and remember, bicycles are not a bad option.
