They will genuinely hate you, there may be a couple who give support but deep down they wished you weren’t doing what you are doing.
You are bringing their area down, you are devaluing their homes. These people don’t want a Motor Trader in their area. They will talk together in groups, they will stare at you, you will be hated. There is no getting away from it.
You will have punters turning up unannounced, they will knock on neighbours doors asking for you etc etc.
The coucil will try to bully you, you will get threats and letters. You will get notes on your cars, they will be vandalised and more. It doesn’t matter how discrete you are, they will be watching and believe me some sad retired bastard make there daily goal to stop you.
Other than that it’s great Keep Smiling to them, be polite, keep discreet, don’t take up roadside parking and fuck em. You have every right to do what you are doing
