Pros: Got a good deal on the used car I bought there.
Cons: The car had been repaired by Shaw's prior to me buying it. The repair work was poorly done and eventually I spent over $400 getting the car fixed correctly by another service shop. When I talked to Shaw's about some of their shoddy work, their attitude was (and I'm paraphrasing here), 'it's no big deal,' 'it's not our fault' and even 'well, you should have noticed the problem.' Basically, it was all my fault that their repair was junk. Nevermind that they put bolts in the wrong place and used recalled parts on the car.
Do yourself a favor. Don't buy a car from these guys. They buy repairables, do a quick repair (of questionable quality it seems), and get them back on the road as quickly as possible. They're more interested in turning a buck than repairing things correctly and getting satisfied customers.
