Updating this thread, in case a fellow fanatic wants to buy my car after a few years and wants to know the full history...
At just under 50,000km, I replaced a pair of the original set of tyres. Yokohama Geolandar G98A 225/65 17 102V. I phoned a few places and went with the best quote - R5,200 including balancing and alignment of all the wheels.
I am making a conscious effort to drive economically, which means using the manual mode on the autobox to upshift at times and trying to not go over 120kmh. Average (computer) trip consumption has dropped to 6.4 litres per 100km on the freeway, but shoots up to 7 or 8 when the roads are busy and cut and thrust driving is required. Long term average is staying stubbornly at 8.3.
The Soul Red paint, while great looking, is a hassle to touch up. I have a few minor scratches on the front bumper, but neither Mazda SA nor good mobile paint repairers can get the correct colour match for my car. Mazda SA advised that I go to a panelbeater and ask them to independently source the correct paint. Needless to say, I am willing to live with the minor scratches, rather than fork out big bucks. I am happy thay my BMW is solid white.
The car is still performing faultlessly (touch wood), but I do know that the brakes may need a check by year end.
The car goes out of service plan soon, so I am keen to see what service costs would be. This would be the first vehicle that I have ever owned that went out of its plan, while under my ownership.
