Thank you again for your comments.
I thought of Rav4,however once I chose the Excel model with all extras ( as having leather upholstery for example, which is quite convenient when with kids as easier to clean) and it was 21K for 17 plate and sub 20k miles. For the same price is 15-16 plate NX300h , similar miles and more extras,more refined, killer look and more luxury feel. Rav4 looks a little bit outdated inside, outside is rather OK.
The same price is RX450h , 15 plate, facelift, 25k mies on the clock, heavy, bulky and very luxurious. Don't get me wrong, just my snobbery alter ego whispers to me : why buying the Rav4 if you can have the RX or NX? LOL.
I know service costs are something to think about. I have already sent an enquiry to Lexus.co.uk and some local dealer for a quote for both NX300h and RX450h for service intervals, cost of servicing + cost of extended warranty. The same enquiry was sent to Toyota.co.uk + local AD. Later, once received the info, I will try to draw some comparison.
The process of choosing will be long and maybe there will be a development and changes in requirements, taste or budget, who knows?
I hope it will not be as long as I was choosing the MB, but I am prepared for few weekends to spend on test-drives and trips to local ADs.
I will be happy to see some pics of yours in order to fuel my fire.
All the best and stay safe.
