If you do everything by yourself instead of having a "professional" do it, you will save a TON of money. For the...motor for the drivers side door controls, new top (which will come with new rear glass attached), passenger side mirror, motor for top and new door lock assembly you are looking at around... $300-400.
Tires depend on what you get...maybe... $300.
Radios you can get a used one on Craigslist for $40. New one for around $60.
So doing it yourself it looks like that will come out to around $700-$900.
I know what I am talking about when it comes to these car parts because I restored a 1993 Mustang
convertible all the way from the headlights to the tail lights and I did everything by myself.
