I know what your meaning about it only been an astra, thats why I said it was a bit to excessive but end of the day if that is his hobby then why not do it to any car he drives, whether it is an everyday car or not.nerd?! its only a bloody astra! for a everyday car that is just stupid!
it may be £7000 but bear in mind it comes with free refills for life you have unlimited of the stuff, so use it regulaly and over a few years it probably works out the same as normal wax, you could even charge to apply it on other people's carsit's a very expensive hobby IMO. the wax he used (zymol royale) cost over £7000. most people couldn't tell the difference between that car and one that had been cleaned with ordinary stuff.
