I sold 230 last year as a one man band, 34 in January 2018 so probably the more you sell/buy the more go wrong, in all fairness i'm not at the price point where I buy low mileage German diesels, i once was and I can recall the precious wankers you dealt with
Last year I'll have had (I think) 6 refunds on cars that were beyond repair and they got shunted in the auction, the secret is to refund quickly, wipe your mouth and then move, keeps the customers happy and stops you dwelling on the loss
ps and around 8 pints a night
you need any checking tomorrow?
sounds about right Simon
