2nd on paradise chevy in temecula being awful. from sales to service its a stealership.
i would add that mark christopher (all gm) in ontario is a quality dealer. Bought my car there 4 years ago. Will buy my wifes caddy there. Only dealer i will ever let touch any of my cars again in socal... figured out a oil pressure issue when i had something in my pickup tube. 4 other dealers told me it was fine.
