Tow bar / tow dolly help

[TexasStig]

I was thinking of getting a tow dolly to transport the Chump CRX locally. TxCoyote suggested possibly going the cheaper route of a tow dolly.
Cheap is good ($69 vs $500-ish).

Bad idea? Any thing I should look out for? I found this on CL:

I'd hate to lower the value on a $500 car.

Having owned a CRX in the past. I am trying to think where you would attach that too.

lostlorin towed his Miata to TMS last weekend on a tow bar.

He has it setup so he can flat tow his Miata behind his RV or Pickup it has been all over the US in the past few years.

He may be a good source of information.

I'm not sure if flat-towing a FWD works as easily as RWD. Might want to pm DavidSS, since he is the resident expert on CRX's.
