My Classic MINI failed it's MOT badly. 

Going similar with mine, got it in June, a 1988 Mini City, was last on the road in 2012, has had a lot done, got it as an unfinished project, but still needs a lot, found rust above the rear subframe so that will need to come off, also bad repairs in the rear arches will need redone, i've had quite a few Mini's in the past though, was also a Mechanic and MOT tester way back in the 90's so that helps a bit.

Happened with my classic mini as well, small hole in the drivers side floor, someone previously put on oversills which has caused the usual rust. Mini is now being cut back to weld in new panels and learning to weld as I go. Missing be out on the road to Tighnabruich. Looking to get all repaired over winter so I can hopefully enjoy the sun.

You need to cut those front inner wheel arches to run those wheels properly

I would look at finding a MOT garage that understands/works on classic cars because some of those issues are a bit extreme. I am in Glasgow and happy to help with any questions or if you ever get stuck mate.

Given the mot may have been a bit heavy handed , it’s still helpful to get a worst case scenario. The rear subframe is a fairly easy job, just watch for the bolts that mount towards the rear seats as they can be a real,pain… mine had ally bolts going into a steel section,and needed careful drilling out. Also might be worth thinking about what type of bushes to use ie rubber v/s poly. Pre the next mot worth taking it to a tyre place with full alignment and tracking kit to get the steering and tracking spot on. Make sure you get the correct sills with the breathing gussets, as the alternative ones trap moisture.

Hey, subscribed to your channel, love your vids on your mini as IV got a couple of minis. Feel your pain on working on your mini , when you've think it's sorted and something come back to haunt you, I'm in the same boat, keep up the good work, it will get better, stu.

Discoloured means they’re not flashing orange so new orange bulbs needed, good time to get LEDs 👌🏻

The mini electrics getting wet at the front and cutting out is a well known issue, British Leyland cured the problem with a splash guard which attaches to three brackets, two on the rocker cover head bolts and one at the bottom of the engine block. It looks like you're is missing?

Parking brake is the handbrake… Probably needs a heel board… They all need sills 😂 I did similar, bought a pretty Mini with 12 months MOT and it turned out to be rotten as a peach. It’s been seven years doing it up… it’s been back on the road one week 👍

Discoloured is the bulb

Mot tester sounds like a knob 😂
