Thanks for all the input. On my first post I didn't want to start chucking out there net margins. ETC. I should also point out that before I went into my current 9-5 I was selling for BMW/MINI for 8 years. So in no way i'm I new to any of this. Like you say the motor trade has a habit of getting under your skin and ultimately always pulls you back! The stock profile is basically sub 3k average Gross £650 PPU. This is all however internet based and is naturally price dependent there was also 1 £1300 loss in there. My feeling's are that by taking the plot, getting a consumer credit license, offering some warranty, a decent website, and having a generous amount of walk in traffic, we could push to obtain £1,000.
Maybe i'm miles off here but I didn't set up on my own to earn 50k a year, probably like some of yourselves you could walk back into a job in the motortrade and make that with your eyes closed.
