Purchased an unroadworthy vehicle

Hi. I had a bad experience purchasing a vehicle at this dealer as it had many problems and one of them hasn't been resolved for over 10 months from the date of purchase. My rear window wasn't sliding and closing properly as they have informed me that the parts were ordered. I tried contacting them on several occasions with no feedback. My driving experience is unpleasant especially when it's windy and rainy as the seats get wet.

I would like to inform anyone wanting to purchase a vehicle at this dealer to be extra cautious since the car also had an engine and suspension related issues
