If favorite means happy... then I don't have any. I don't really remember the make or model of the car... but I do remember it was free (a gift from my aunt after my cousin beat the vehicle up)
I was warned not to drive fast and aggressive - the engine couldn't handle it - but I didn't listen. Within 24 hours, my very first car was dead. It had overheated and I was stuck on the side of the road... only 100 feet from my house at midnight, and having to push my car all the way in the driveway. It never started again!
So, I guess my favorite memory was that it was free!
