I've owned a couple of quasi supercars. I don't think I'd ever go there again. In the UK it doesn't inspire appreciation. People just tend to think you're a flashy twat.
Staying under the radar is far more peaceful and more fun. I'd go for a stinky old banger with a few hundred grand's worth of WRC technology bristling underneath.
I imagine it's fun for awhile but the attention would get old unless you crave it. I've heard many people say that's the reason they ditch their dream cars even though they love driving them. Saying that..it would be great to have one for the occasional ride. In my location it's super unnecessary and you must be super rich as upfront cost and maintenance are stupid compared to the U.S..and the roads are not super car worthy.
I'd like to have one on some kind of timeshare if I ever end up spending time in the U.S again..and, well, btc makes me wealthy again lol.
