My mechanical knowledge is practically zero so I'm not sure of all, but the main problems on the old car are:

Loud grinding sound from the brakes. Needs new brake pads?
Loud ticking sound from under the bonnet/hood, timing belt going?
Bonnet/hood cable is broken and therefore it won't close properly. There's a safety catch so there's no chance of it flying open when driving, but it will jiggle around and jump up and down at speed, which is distracting and doesn't look so good.
Rear exhaust had a small chrome clip when I bought it (just for cosmetic purposes). Recently I noticed that had disappeared along with half the exhaust pipe, which had rusted off. Technically it's not an issue but again it doesn't look too good with a broken exhaust pipe.

All the electrics still work, including the windows. The drivers seat is worn down but still comfortable. It starts and runs every time and has never let me down on that level. The mileage reads about 176k but it's had a reconditioned engine at some point so it's not known how much it's done on it, but that engine still runs very nicely and has many miles left on it yet I'm sure.
