1:24 Bmw M3

Hi. This is my first model (Buraggo BMW M3 GTR 1:24) . I've just done the intercooler and put it on the engine. I'm also working on the turbo. I want to ask you about the paint of the body. It's going to be black, but i want to know should i strip the white paint first, or should i spray paint the black over the old paint?
Here are some pics:

Nice, is it Bburago model ?

Ooops yeah. Made a typo, yes it's a Bburago.
Thanks for your tut on intercooler. It's very easy to undrstand and easy to make. Btw how did you paint your BMW. (i can see taht they are the same models :) ) Did you strip the old paint off or did you paint over it?

if the original paint is pretty good with no chips or scraches it will be fine to just paint over it but make sure you wipe it clean first to get rid of grease and fingerprints it will save alot of time stripping the paint

Actually was my M3 that colour when I bought it and so as Escort. :)

@Howey: Thanks for the info. The original paint is very smooth and has no scraches, so i'll paint over it.
@Visible33: Yeah. I looked at your pictures later and saw that the paint was the original :)
I'm going to wire and paint the engine today and i'll edit this post with pictures. :)

EDIT: Ok, i painted the engine. Visible33, i used your way of puting the turbo on the engine, because i couldn't think of another way. And there isn't much space in the engine area so i think that's the best way. I'm working on the body paint now. It's a little bumpy now, but i'll polish it. Here are two pictures of the engine:
