was too good to be true... I phoned back to change the date, and they asked me to confirm that it was the major service I wanted, to which they re-quoted £382 (discounted from £424) for a major service on the R32
I asked why it was almost £100 more than the >2 litre engine major service, and they said the spark plugs cost £16 each on my particular model and requires more oil.
If anyone else on here has an R32, I'd be interested to know what you've paid for a major service!
