Last night I went to see a car at this location. It was CLEARLY marked NOT FOR SALE on the windshield. Friend out of state had been speaking to a salesman at the location. The car was FILTHY and I found errors in the listing. Understood why not for sale yet. First thing this morning my friend got a text saying it was SOLD? Really??? I left there at 8:15 last night (closed). When did it magically go for sale? I WILL NEVER consider this dealership again.
