Everything that goes wrong, and it's only a handful of things, happens between 80-120k miles.
With this car, I cannot help but think that instead of worrying about what a model that will never exist might be called, time and effort might have been better spent actively researching the common issues and how best to approach them... and I wouldn't be at all surprised if the next thing we here about is that it's up for sale because this fantastic garage wants £1,500 to change the wishbones
Don't get me wrong, I probably spent £2,500 on my plod one over the 175k/seven years I had it for, but after 275k, it had never needed an oil cooler... as for Vauxhall service schedules,
Oil and filter every 10k, (5k if you're bored or do alot of short journeys), plugs, air and pollen filter every 20k, coolant every 2 years/40k and cambelt every 4 years regardless.
I would suggest that your car has been mechanically neglected and that you are now paying the price.
