No doubt in my mind that Lexus has remained a niche marque in the UK partly due to the narrow choice of engines in their line-up. Agreed. It might have been different had they done so and we might not now be discussing this thread.
I’ve attended the Goodwood Festival of Speed for as long as I care to remember and it was only just recently that Lexus had a stand there. It is the UK motorshow and has been for years. The Audi, Merc, Jaguar and BMW stands were always rammed full with people. I repeatedly contacted Lexus marketing to ask them why they didn’t attend it. When they finally did only fairly recently my mate - a dedicated Audi fan - said he couldn’t believe how good the cars looked on the Lexus stand and he’d have been tempted to give the NX a look instead of a Q5. How many people might have been tempted to have a Lexus with a bigger engine choice for each model and some determined marketing. Very sad really.
