Had service done here once. Now I just got telemarketed on my cell phone that they want me to trade my car in as part of their "upgrade" program. Then they denied that they were trying to sell me a car and said they wanted to just buy my car, and I asked, "How it is an upgrade if I have no car?" They are raiding their service records for telemarketing calls, which means they are likely selling the records to other telemarketers or worse.
