Time to move on. This wind shield will not be an issue for 99.5% of the population. I will contact a few dealers over the next couple of weeks and see what is on offer, both for outright sale and trade-in.
I will consider the new Astra Wagon, UK built by Vauxhall, also the new Suzuki Swift, Japanese built, and the new UK built Honda Jazz, if it arrives in my country this year.
As mentioned in the post above, it must work for me, no vision compromises, or, its all over for driving. 8,800km in 6 years was, indeed, a fail!
Edit: An update: After a call and suggestion from the Auto Club Technical Advisor at RAC WA, I contacted Australia's leading auto glass company, O'Brien Glass. They are sending an experienced assessor to look at the car and diagnose the true issues with the windscreen glass. More later!!
Later: In preparation for the inspection, I decided to clean the windscreen. First I used Glass Cleaner, this produced black residue on the paper towel, so I went for something stronger and used Gum Turpentine, this produced much more black residue. Once the black stopped coming off, a clean with Methylated Spirit removed the oily turps residue. The next morning I noticed the blue stripe across the top had changed to black and the ripple in the stripe was no longer visible. On closer inspection the other ripples has almost disappeared. After a couple of days, all the ripples have returned, but to a much lesser extent. I then found the car to be drivable without any major problems.
I then took the car to O'Brien Glass for their inspection, it passed, the manager identified some minor glass distortion, but not enough to be concerned. What a difference a good clean makes! (I chamois all the glass before every drive)
Edit, Update: A couple of weeks back I fuelled the car and tried to return home on a 90km/hr road, however I was not able to see any distance and focus to drive much above 70km/hr. The ripples just return.
The wish-list has also been changed.
The new Astra Wagon and the new Suzuki Swift are off the list, similar glass distortion issues for me.
Also the Honda Jazz is also out, too many interruptions in the visual field.
However new additions to the short list: Volvo V40, Subaru Forester, Toyota HiLux, Honda City.
More later.... Edit: The Volvo will need individual evaluation as they are now fitted with Left Hand Drive windshields.
