Yes, surprisingly... I am. Capped price, all items as oil, filters etc... renewed (im a person that actually checks it.....) and included in the price, it even shifts better as it already did with the shortshifter so don't know what they done, updates checked and they even washed it inside & outside.

New battery as I woke up on Friday to discover mine out of juice. Less beer tokens for the weekend

Quick question... stock SRi rims 16x6 and ET49?
And if going to 17x7 ET 38-45 do 205/45 have any clearance probs at stock height? How about 17x8 215s at same ET? I'm thinking 17x8 is too wide?

I'm thinking 7.5" width is going to be the max in a 17. On a 7" rim though, I believe a 205 wouldn't be too much of a problem. Only thing is, I'd go with a 205/40 as opposed to 45 series. Mainly due to the speedo factor, as with 195/45R16s being standard, going to a 205/40R17 increases the overall rolling diameter by just under 7mm. Going to a 205/45R17 increases it by 17.2mm, which also puts you on the wrong side of the law in some jurisdictions (I know here in SA, you can fit whatever size wheel as long as the overall rolling diameter isn't increased by more than 15mm over stock). I used this calculator for those measurements: http://www.exploroz.com/Vehicle/Tyres/SizeCalc.aspx

205/40R17s aren't that expensive from what I've seen. Kumho KU31s go for around the $90 bracket plus freight or KU39s around $110 each plus freight. Then I guess you need to factor in fitting, etc. and some tyre places will charge $20-25 per tyre for that alone. Guess it's a good thing I have a mate that can do it for free.

Good stuff...I'm due for my first service next month. Just hope it goes well too.

Yeah think i'll stick with 17x7. Was thinking more 205 than 215 as well and 40 or 45 was going to be my followup question There's some good calculators online that tell you how far out the speedo will be, how much further the wheels will be to the shock or stick out etc.
To the original question though... stock wheels are ET49? Seems a lot vs other FWD cars.

So after being advised best to run 38 to 40 psi tyre pressure on the Astra, I did check the pressure. 40 psi indeed, done by the Holden dealer 2 days ago during it's service (though the sticker in the car recommends 34 psi). Makes for a hard ride so I adjusted it to 38 just now and see what the difference will be tomorrow.
