Hi Andy
Here's a few of my thoughts for what they are worth
As said, a lot will be dependent of cost coupled to the revenue & market exposure that you hope to achieve.
From a outsider's point of view .... The Saturn brand has had some great exposure in the CKC magazine ( How has this past exposure worked for you )
Any avid/regular reader of CKC will know the Saturn brand & the concept of what you are all about
With your buisness head on, it may be time to compare the circulation/sales figures of the various mags out there .... Total Kit Car & Kit Car etc
It maybe the right time for you spead the word via a new publication & reach a new market exposure audience !!??
If CKC has offered you a great deal, I am sure the sales team of a rival publication will do their best to at least match it ( They are facing hard times too )
That's about the best this old duffer can come up with
I really have to commend Saturn for all that you have achieved so far & the true dedication to the whole Roadster concept
