I'd exercise caution with this purchase. This may be one of those "Send a deposit to hold the vehicle" scams.
This is supposed to be a Texas vehicle, but it's advertised only in Colorado, and not on any Craigslist in Texas I could find. The asking price is at least $5000 lower than other comparable vehicles. There's no phone number, only an anonymous email address.
On the other hand, it could be legit. It pays to be suspicious of this sort of ad.
