While we tend to be more anal about details than civilians might be, 1 of the primary reasons for RWG's existence is to educate the rep community. To that end, I think it is always advisable to get input from others (with relevant knowledge) before clicking the buy button. That way, both sides win. On the other hand, if the seller feels you are being unrealistic or if the issue cited occurs on all the seller's reps of that model & the buyer is unwilling to accept it, the seller can cancel the sale & neither side feels taken advantage of.
