I have a 2001 C5 Z06 and a 2006 C6 Z51 Stingray. I will put the Z51 up for sale in about a month. The C6 Z51 cars list for around $30 - 40K, so a lot less than a Z06. I love the wide body so am looking to upgrade when I can. The C6 Grand Sport was only made from 2010 to 2013 so they list for just as much money as a 2006 Z06, around 50+K. There is a lot to know about each model and I enjoy doing the research and learning about them. Once you know what you want (what model, what year(s), auto vs manual, interior \ exterior colors, options, etc) then you have to try and find that car. I search Canada wide and would travel anywhere in the country for my "perfect" car. The USA used to be a huge market to import from, however, with our low dollar and the crazy high prices in the USA, I have not found any bargains down south. However, if you are very fussy and want a very particular model, then importing from the USA could be an option.
