Camera and lense????? which one to get

[evilbert]

Hi guys, one of my first posts but i have read a lot of the "which lenses to buy" threads which have been really helpful but i am a complete newb to 'proper photography', I have never had a DSLR before and have tried my hardest to get pics with my Fuji 4900 but to get cars that aren't blurred i have to turn the shutter speed up, which in turn gives me very dark unusable pictures.

I dont have a huge budget (around £300) but there are so many different makes and models i just dont know which body to get????

i will be working indoors in very bad light and will be taking pics of Micro cars going very very fast....

I have been told that Nikon is the way to go and have been looking at the D100, is it good enough for what i want and what sort of lense do i have to get to solve the dark image problem i was having with my old camera?

any help is very much appreciated.

Thanks in advance
