I want to fulfill my childhood dream of an L322.

Long time lurker of all things rover, coming to the great people seeking advice and encouragement. I’ve owned many brands of European car. However, the one that has always been at the top of my list has been a 2010-2012 L322 with the Supercharged 5.0L. I fell in love with them as a kid, seeing them on the road with so much presence and class! But I could never bring myself to buy one, out of fear for repair costs and reliability. Now, I’m seriously considering selling my current BMW, and buying one. I’ve researched the common issues for years (timing chains, air struts/pump/valve, control arm wear, cooling system leaks from plastics, tailgate rust, injector failure, etc.) and I know that it wouldn’t be a free ride. I’m planning on budgeting 3-5k a year in maintenance costs, on top of a ~15-18k purchase price. So, should I do it? Is it worth the magical experience? Are the 5.0Ls really as bad as the internet says?
