Somewhere in the middle of that I'd say for a typical conditioned example for that mileage. There's quite a wide spread from neglected basket case to... extreme, one owner, fastidiously maintained/garaged.
Good info... Thank you! My car is definitely somewhere in the middle. It's certainly not a basket case but it wasn't pampered either. It looks to be in decent shape, I'd guess I'm the third owner, I found the original manual in the car.
No mods that I see, the console lid was missing and the convertible boot, but I've replaced both... The biggest issue is probably that oil leak and the rear window is separating, which I forgot to mention.
