That's a good call and probably the way I would go too, although that orange McLaren is very beastly as well. When I was out in Vegas I took almost that same car out on their track out there, 720 is one hell of a car. Although they said that it was constantly having issues
I've never owned a merc that didn't have *some* laundry list of "recommended" repair at the dealership.
They still run, and aren't a serious risk... but it's always xyz flex disc showing stress cracks, xyz ball joint wearing, xyz gasket with minor leakage, some steering piece, front brakes at 40% but you're good for 40k or so miles, rear brakes at 15% but you're fine for another 4-5 oil changes..... even if I dropped all the cash and had everything fixed at once I have no doubt the next visit there'd be 5 new things on the list
Still, loved every single one of them. Except my sister bought a c class in the early 2000s. That wasn't my favorite car, but, then again it's entry level for a reason....
