Thank you all for your sound answers.
Well, I guess the spirit of wisdom came over me and I'm now the happy owner of a good ol' Honda Jazz from 2003.
Better start with something small of little value that I can use for practicing my driving skills, and, worst case scenario, get scratched without worrying too much.
My wife is rather happy in fact - there is some charm in having a humble first car, we're young and it'll create good memories. The stain of pain on the bonnet make us laugh.
I still got the eyes on Lexus however, probably will make the move in 6 months or so.
I think you are right - I might save a bit more to get a more recent model or one of a lesser mileage in good condition.
Logical alternative indeed - however I've heard this model is significantly noisy.
It'll have to be the SE, for all the reasons stated on this forum
Indeed it's thirsty. When budgeting at purchase, I add the yearly cost of excess of consumption compared to the average car to the price of the vehicle. Therefore, once factored in my budget, I can drive with peace of mind for at least a year.
