Even though you ruled out the 3rd one, I wouldn't. Mostly because it's got the least miles AND the original engine...probably.
The other two have different engines AND, unless documented, might be out of higher-mileage vehicles.
Still, ya gotta like the 18" wheels and price of the detaildriven unit. He'd probably be the type of guy to produce documentation for the engine.
Color is a personal choice. That should play into your choice.
That 2nd one -- touting 20-25mph with the TOD mod....I'm not convinced he's telling the truth on that. And, anyone who stretches the truth, might massage over other "issues". Like how many miles are on the rebuilt engine. Or, even the quality of the rebuild.
