Mr. Hill

I've been lurking around the board for over a year now and finally became a member. The main reason for posting now is that I've got a 98 black Z28 with some minor mods; exhaust, lid, sportlines, programmer etc. The problem I have is that I'm moving into a position where I could 1. Sell my Z28 and buy a C6 (the Z28 is my daily driver and the C6 would be the DD.) SO here's my prob either pay $30K for C6 or dump some cash into my Z28. Figure 3-4K in paint and $3-5K in a motor and maybe some other mods to make it more enjoyable. So spend $10K on a 12 year old car or spend $30K on C6? I know the maint. on the vette will be higher, Tires, windshields parts etc is it worth it or should i keep my Z28?
