Question about the Colombian Tegu

[Corey209]

There's a local guy who's really wanted my ball python for his breeding projects, he's the same guy who also pretty much gave me two boas for $40 because he needed to make room. He's offering me a 3 foot B&W Colombian tegu but I'm not sure if I'll be able to house her properly.. He's willing to give me the 55g that comes with her but that doesn't seem like a good size and I don't have the room to turn an entire portion of my garage into an enclosure.
