Reading through this thread...based on my 10,000 mile and 18 month experience with the Aero based Plus 8, which is, according to MMC, a Supersport with a different body....
Front suspension noise...yes, they all do that sir! In this case it is normal when the car is cold as the joints are all metal on metal. There is some adjustment possibility, Tarka was quieter after the service last year, but it seems that 6 months later the noise is the same. Once hot the noise disappears.
Steering pump noise..on full lock (which isn't much of a lock) the pump bypass valve squeals. This used to be common on power steering systems, 20 years ago. As long as the fluid level is OK then there is no problem.
Petrol Smell...shouldn't happen.
Idling...cold steady at 800 rpm, drops to 500 rpm as soon as it has started to warm up. With A/C on it idles at 800 hot or cold.
Warning light failure... it seems the circuit board that holds the row of warning light can fail through damp entry...and subsequent corrosion.
Door opening....well doesn't apply to the Plus 8....bog standard trad doors and side screens...MMC seem to have making them down to a fine art.
