My old sunbeam is insured under Hargerty Classic Insurance. I get the magazine each quarter and they had an article on what cars will be the next potential classics. They listed the Pontiac coupe of course as one and also the Saturn Sky Redline. I will try and scan and post the article this evening. Was having technical issues last night and I cannot access the article on line since it just got mailed out. Hagerty also has done a study of the effects on E10 to older cars and it is a very informative study. Seems E10 actually has little on no bad effects on our classic cars unless they have the original rubber/cork seals and E10 will wear them out sooner but not just eat them/melt as so many claimed it would.
