So I'm looking at buying a used '06 M7 EFI or an '07 M8. Both are 162" and both have about 2,900 miles. The M8 is going for about $1,000 more but I'm not sure it is worth the extra $$. I have heard great things and negative things about both sleds but want to know if there is a reason I should go with one over the other. I have heard that the M7 is more of a revy engine but the M8 is said to have more HP. Any input would be appreciated.
