Taka,
You aren't wrong mate... I got my Z3 M coupe fully resprayed by Mr. Gloss and they really looked after me.... and then its engine bay and other bits resprayed by Charlie (with engine out)... I am Charlie's customer for nearly 10 years... their quality is really up there... and with Mr. Gloss, they are as good... if you are paying out of your own pocket, go to Mr. Gloss... and if the insurance is paying for the job, you can really toss your coin here... I will go to Charlie because it is closer to my home... however... Mr. Gloss is just 2 minutes from my work and close to Andrew @ Southern too... I wouldn't want to make this type of decision any time sooner though....
I am sure Andrew will prefer Mr. Gloss over others
cheers,
richie
