One man band 20 years last week ! To be fair last 3 years not had a holiday - various reasons BUT in my early days closed - divert phone to an agency and didn't really care if I lost business as that's how you have to be or you burn yourself out.
Now I have a friend , not experienced at all in car sales but helps me out , he can deal with customers he will sell under instructions , can't value cars but holds the fort , mans the phones , keep an eye on the place and takes messages , if he sells while I'm away its a bonus ! ( If genuine buyers they will leave a deposit and come back if explained to them !)
Matt - Pack your bags and enjoy some 'quality' time with the misses !
