Xenon Headlight blew 3 weeks into ownership. Dealer did not want anything to do with it. After a quiet work and the mention of a call to a solicitor, they agreed. It was found that the headlight had come free from its fittings. This was £90 for the bulb and £40 fitting. I did not have to pay, but at least you know how much.
Run-out on the brake disc's at front was excessive. £100 and fitted them myself. Easy to fit.
The car eats through tyres like Pavarotti in a spaghetti eating competition, if you select the wrong type of tyre. Get a hard wearing tyre like Pirelli. Do not get Bridgestone. They are way too soft. Pirelli do the best job. 10k miles and still only worn half way. And I do tend to be a bit lead footed.
Power steering pump replaced at 68K miles. £450 (inc labour)
Rear bulbs blow every 2K miles. May be a built in feature.
Do not use main dealers. Search for a local garage with someone who has experience with Vauxhalls. You will find the prices cheaper; they will not ask for the shirt from your back and give your car back with more faults than you started with. But do search.
It is black so a pain to clean, but looks great when it's done.
The best thing, apart from performance and the built-in telephone system, is the rear blind. I noticed someone else also loved this feature. Thank God I am not the only one.
As for performance, it really is a great car. I recently had a bit of fun with a BMW 328i and an Audi TT. When they caught me up at the traffic lights they were a little surprised.
I am still smiling.
