June 2012, I purchased my first Vette. I quickly learned and found great joy in my 94 coupe. After "cutting my teeth" on a C4, I am considering upgrading to a C6. Last night I took for a lengthy test drive a 3 year old C6 Coupe with less than 5,000 miles (automatic tran.). The car is what I expected it to be. It certainly is like new condition, but I have one concern. Throughout the test drive, I kept smelling "smoking oil" (as if some residue oil was dripping on the exhaust manifold). Returning to the dealership, I inspected the engine compartment at length; and could not find anything. When the car was pulled back in to the showroom, I caught a wiff of the same smell at rear of the car. This especially struck me as "odd". So...the red flags are up....What do you think might be causing this? Is there a possibility there is an engine problem? Has anyone else experience this situation? Thanks.
