Jim was a great person to deal with. This was the second vehicle we bought from Jim. Both times he made it a pleasure to car shop, instead of the ordeal that it usually is. Easy going, k This was the second vehicle we bought from Jim. Both times he made it a pleasure to car shop, instead of the ordeal that it usually is. Easy going, knowledgeable and most importantly, not pushy! We will definitely be back if we ever need another Subaru. This is an awesome vehicle. I'm still surprised how much I like this Outback. I've told several people looking for a vehicle to go talk to Jim. They won't be disappointed. More
