He'll have to go with a 912 for that budget. People here are always blasting Beverly Hills Car Club, but they have a ton of 912s and 911s for somewhat reasonable prices (on some of them, anyway). The wrecked white '65 911 is a bit steep, but it demonstrates the huge cost difference between a 911 and a 912, such as the red '65 right below it.
