Thanks for the comments, everyone. I really gave it to my younger brother to drive it now. I really don't think its a huge sacrifice, I mean my brother wants my mother to buy him a honda accord, so in order to save 10 grand, i let him have the Impala. After all I don't legally own the Impala, my parents just give it to me. I got the Corolla for free from a friend of ours. I've put a lot of money into it from tune up to tires. Almost $1,000 put into it, so you know I'm going to keep the Corolla for a while. The A/C in the Corolla works good, just may need a new expansion valve or compressor, since it's not as cold as my pop's Silverado.
