Everything runs well. Never thought i could have the perfect car for such a good price. If you're looking for a great car that runs perfect and smooth rides i recommend this! No need for upgrades as it is already an audi and audis are the best like totes mcgoats the best. I rode my kids to school in this and they love it waaaaaay more than the mini van that we had before! I highly recommend this to people as it is probably the best car out there with a decent price.
