1999 Lexus GS400 - Needs some work

Overall the car is in good shape. but it does need some work. I am selling it as-is. I would be happy to answer any questions and provide any pictures requested. The following are items that I know of that will need repairing:Needs a new brake booster assembly (the current one is working fine as of now. but it sometimes makes a squealing noise and the buzzer and ABS lights are going off)]Check engine light is on. Possibly related to the oil control valve or VVT solenoids. The engine starts and runs fine. but misfires and idles rough and once it is warmed up. The A/C has a VERY slow refrigerant leak (a single refrigerant refill lasted about 2 months. so I never bothered fixing it)Things I've had repaired:Timing belt replaced around 125kValve cover gaskets and spark plugs around 135kReplaced alternator around 135k Front brakes were done about 500 miles agoSome exterior work may be needed:Rear passenger side (behind the wheel well) was slightly damaged when it belonged to the previous owner. Front passenger side has a small dent above the wheel. Passenger side view mirror cover is crackedRoof paint is chipping
