This car sounds SO BAD A$$!! I have been giving the mother's their rides (my MIL and my mom) and the car totally frightens them. With my mom, in particular, that saying something because she has ridden in quite a few thunder-wagons since she and the ole man started dating 50 years ago!! I'm not even getting on it hard, yet, but when that 6.1 start to breath deep they start grabbing for things . There may not be a pass-through but that is one thin firewall.
