Perseverance paid off for Marsha Coulthard. The 43-year-old medical billing clerk and HGTV fan said she "entered almost every day" in the HGTV Green Home Giveaway 2008, which offered a new green home and a 2008 GMC Yukon Hybrid as prizes. Coulthard won the house and SUV over the weekend after her name was drawn from among over 21m entries. The house is large (three bedroom, 2.5 baths in 2,000 square feet) and was certified Gold LEED for efficient design and construction. If you want to take a look around inside, check out a virtual tour of the house here. Oh, and feel free to make any comments you like about GM not being able to sell their large SUV hybrids, so they have to give them away.
