I bought a Buick Rendezvous from Long. On the whole, the price was fine. The Finance guy was a real ass. I nearly walked out. He was pissed that I got an Warranty Direct extend warranty. The service bay is clean. To the point that I am not sure anyone works there. The service people are not all that sharp. For almost a year there was an issue with the speed sensor. They replaced everything but the speed sensor. Finally, they planned to tear apart the transmisson. I got in a fight with the service manager. They finally check the speed sensor. They wiring harness on the sensor had cracked apart.
I just went to them for body work. They sent me to Brigham and Gill. They wanted $1700. They actual repair was done at Muzi for $700.
Long is no better or worse then the rest. The service people are not that sharp. I would buy another car from them but service it elsewhere.
