should i wait until summer to sell my car?

nah they dont, ive sold 6 cars in the past 10 years and no-one ever took it to a mechanic not that id even let them, might never see my car again, and youre also wrong about most people really looking over a car, most people just take your word at face value, ive sold cars in worse conditions than this one for good prices.... there was a car i had once that needed £1500 of repairs done to it and i sold it to a guy for a £1000 and seeing as i only bought it for £1000 it was an OK deal.. i just told him it needed new brakes and a new seatbelt, but reallly it was completley fucked
