If your a petrol head with a passion for such cars then why the hell not?
I’m running an 18 year old 735i V8 because I love them - had a 728 years back and always wanted another - it’s a one owner low mileage example yet I’ve spent £1500 on it this year so far in servicing and preventative maintenance, it’s a passion for me and I’m more than happy to do so.
But to want a car because it was “your car in Gran Turismo” is bloody nuts!
You may well find insurance relatively cheap but that’s where cheapness will end, never mind your lack of driving experience, a recipe for disaster if you ask me.
Get something sensible.
