Welcome MrM3. I would recommend purchasing and servicing at Jessel. I've been problem-free there for 4 years so far. Two purchases, countless referrals to buy, and service without issues. PM me when it's time for your next car if you like.
I didn't have much success with my one and only service experience at AutoWest. Went south immediately after I answered "no" to their first question: "Did you purchase your car here?"
Enjoy your car!
