Anybody know where the best deals are on enclosed race car trailers? Looking on the net...... prices seem to be all over the place, and not many in stock... Suggestions???

  I'd tend to stick to the name brand stuff.  Some, not all, of the no name stuff on the internet is real crap.  Bad designs, frame members too far apart, thin ply or OSB flooring, paper thin siding, etc., etc.
I've looked at stuff friends have gone way back to the midwest or deep south to save a few bucks on and a lot of it is junk I wouldn't haul chickens across town in, let alone my race car hundreds of miles down an interstate.
And you won't get much back on your investment when you try to unload it on some other poor schumk.  A good trailer will last for many, many years.

The majority of them are made (or the metal comes from) in and around Indiana area.

The (about $3000) price difference, is usually shipping costs.

I bet you can get a basic 24 back east for $4900-$5900 zone

Then you schedule a few Uship jobs along the way, and pay for your trip
