I have a few.
1) I'd like to sort out the changing of socket covers in my house started years ago.
Not being in the market for 240v AC to be applied to my body I used a plug in light to check if sockets were shut off so I could do the wiring involved when replacing power sockets.
There is one socket in my house which remains live when I switch off ALL the fuses, which is scary enough.
Bu this also remains live when I turn off the main breaker to the house.
I'd like to sort this, or wire everything else into it if it is not on my bill.
2) Sebring MGB
I have an MGB GT in my garage awaiting me to become rich and pay someone to restore it, or get a better welder. If/when I do I would fit Sebring bodywork :
And add a tuned TDI and 6sp instead of the (yawn) Rover V8 and Range Rover box. The MGB is quite light (compared to e.g. a Golf TDI) so I think it might "Go" quite well and use very little fuel.
3) I want to get a cheap 106 / Saxo / AX 1.5 D and mod it a lot in terms of lightness and using veggie oil in it. All of these cars are more or less the same.
