Used Car dealer

Hi everyone. Does anyone have any recommendations for car dealerships in and near Reading. My last car was an absolute catastrophe and I’m planning on investing a good chunk of my savings in a better car. I see 100s of cars on auto trader everyday but I really just want to go to someone trustworthy because my knowledge about cars is limited plus I’m honestly a bit traumatised 😂 I do not have any friends who know cars either so any help would be appreciated!
