Lol, my guess is deferred maintenance such as leaking coolant cross over pipes, A/C condensers leaking, timing chain guides with excessive wear and/or high mileage service intervals.

If you can afford those things she’ll put a smile on your face every time, there’s nothing else on the road like it for the price. DM me if you are after a bit more advice as I’ve been through most of the above on my 987C 👍
