Bud, I certainly don't look down on a SB car...in fact, I was watching the auction on the gold car before it was ever posted here because I had an interest in it. I think you are taking my (our) thoughts on the monetary value of the car in question as a judgement on how cool the small block cars are in general - absolutely not! Frankly, if that was an RS/SS 396/325 car in exactly that same shape with 88,000 miles I don't think it would bring $30K. If it was a low mile car - maybe $25Kish at this point, but an L48 would need to be really special to bring $30K.
I'd love to own Denis' new car. Put a new paint job on her and a little detailing and she would be sweet. The L48's are much more streetable than a Z or L78. He got a great deal on it, but there have been others on ebay that weren't too different for far less than $20K.
So take it easy...we like SB's too! If you come across a nice one with tons of options, let me know - I'm interested
