That's what I did. Bought a built race car minus the engine. It wasn't turn key by far but he cage and suspension was already there.
Ask around at the track and watch racing junk, get he word out you're looking for a race car. My first season I didn't have a trailer either. Rented a 24' enclosed for my SCCA school and then rented an open trailer for one more event then found my current trailer for sale locally. It's an open trailer but has a tire rack and a long 3' dove tail. I bought it off a local dirt track racer so watch he local dirt boards for deals too.
