Help me!!

I have old Honda Accord 1980, I want to upgrade it to Honda Accord 2003 step by step.
I do not much money right now.

Please Help me about this, which parts one by one I must change. Thanks

I had an 81 Accord, I "upgraded" it to a 95 Accord by buying a new-ER car.
You can technically "upgrade" the majority of the parts off a 03 Accord into an 80 Accord, but why?
Just get a newer car. Or am I just not reading your question correctly?
