I would say check out Privage Sellers, Its the route I went.
Some ones I would consider-
2007 LT2, $23,5000 63k miles. In Nottingham (49miles)
2001 Z06, $16,500 64kMiles (Reston 60) but if you go C5 IMO go stock or 03/04 Z06
2005 $19,975, 57k Miles, (Bedford 69)
2002 $13,995 79k Miles (Manasas 72)
If you fix your own cars, I would check out- 2003 Z06 for $15,500 with 116k Miles on it. Good price if is a Z06 and you don't mind the miles
Or just buy from a guy on here. I'm a little further than 150 miles but I'm kinda trying to sell mine lol.
