Have you talked to Micheal at Sunwest Motors? He's in Ventura on Palma Dr. and may be the same guy esmit208 is refering too. If you'd like to give him a call, his number is 805-644-9644. I live in Ventura and have had him as my ONLY Z mechanic for 22 years. By the way, if you're in a BIG hurry you'd better let him know in advance because he likes to take his time and do the job right. I've never had to return my car to him for not fixing it the first time. He's that good. Tell him Rob refered you to him.
