LX 600 is not a difficult product to one-up: it’s deficient on power, luxury, technology and features.
With that said, this is Infiniti we’re talking about - a brand hasn’t had a home run or even a good showing in the last 20 years. While the LX is vulnerable, I’ll be curious if Infiniti even has the ability to kick Lexus while they’re down.
I think an ass whipping from the QX 80 would be a great thing for Lexus - they need it and they deserve it. Looking at history, I’m not just sure Infiniti is fully capable of dishing it out but I hope so. More competition for Lexus would be better.
