Odd comparison.
Steering in the 3IS is as good as a BMW. Actual driving dynamics are a bit short. 3IS steering and driving dynamics are night and day compared to our 2IS, though. The F Sport package is a requirement to feel sporty. Though I'd hold off from the IS, as I believe it's due for a refresh in 2019, so you might score a deal on an outgoing model. You could get the GS F. Dealers routinely offer 7-15K off here. I personally don't feel comfortable in the 3IS compared to the 2IS. The 3IS seats are a tight fit for tall individuals. It's a great looking car, though. I won't deny that. I don't mind the Predator grille either. What GS?
The new 5 will or may be coming out with its own M Performance power and sound kit within the next year. If you're not in a rush. I don't know the true figures for what a B58 from a 340i puts out, but I recall it putting out close to 380 with the MSPPK in a video or two of owners who dyno'd their car. As you will know, the Germans love to sandbag their performance numbers.
I'm in the same boat as you though. I need or rather I want a new car and am waiting to be a year out from the E wagon, and 2018 will mark four years on our other car. No plans on getting rid of the 2IS. That car is just so damn useful around town. I think
@A.Goldberg's father recently bought a 3IS or I've got him confused with someone else. They are very good luxury cars that are easy on the wallet. What's held Lexus back for a long time was powerplants and their navigation software. Lexus is pushing the envelope, albeit slowly, with their powerplants but their software still needs work.
Not making a joke here, but have you guys considered the new V6 Camry? I think it looks fantastic and sounds great for a Camry.
