I had an NX 300h Luxury for a year up until last November, nice car but decided SUV is not for me. We were on holiday in September & travelled all around Spain in it, average MPG was 35
I bought an ES 300h with premium pack (69 plate so last before the 2010 price rise and so even with premium paint (mesa red) just under the £40k price new so no higher rate VED.
Obviously less boot space & no folding seats but it’s adequate for me I also purchased the modified boot tray to fit a space saver spare wheel (separate post in this forum). There is less wind noise than the NX but obviously access is more tricky with the lower seating position. Mine is almost Takumi spec with heated & ventilated seats with memory, extended seat cushion (electric), rear sun blinds, BSM etc. On a run last week to Ipswich & back (320 miles) I averaged 48mpg. I also had the Apple Car Play upgrade done.
Horses for courses, I would test drive both. I absolutely love the ES but that’s my personal preference to suit my lifestyle
