The repairs made a huge difference, it shifts nice the issues it needs is
the exhaust has no catalytic converters so it runs lean on start up, slight miss here and there
once the car is fully warmed it runs good
it looks that the core support was damaged and repaired at one time
the windshield has some chips and small dings
the airbag light flashes 10 times, sometimes it stops
the auto adjust mirror switch doesn't work in both directions
air conditioning is not real cold
cruise control doesn't work
horns don't work
the door seals are torn on the bottom from getting in and out
