You’d probably need to go with a kit car to get points 1-4. Maybe something like the Tabby EVO? You’d probably have to do more DIY than that though if you want point 5 as a four seater base will net you nearly €25k.
I also wish someone would fill this niche with affordable complete cars. I’m guessing capital costs are the barrier from someone hopping in?
