See above. OP already said 2k bonus from credit card. The rest was from the 5% earnings from spending on the credit card.
Congrats! That’s amazing deal. As far as the Ackerman effect, sadly that’s a common complain for all corvettes! I’ve been having the same issue and took it to the dealer twice and they said it’s normal!!! It gets better during hitter months as tires warm up. Get real nasty on wet and slippery roads.
RobC2 how do you figure $665?
The GM card earnings are like money down. Since $2k of it was a bonus though, that makes it better, but I didn’t know that at the time of my post.
