I might be a good person to ask, since my car recently got back from Robs shop (about 2 months ago i think)>First off, Rob is a real nice guy, very knowledgable and helpful. When i had my car trailered there he was really busy, but he took my car anyway. After 5 weeks, maybe less it was ready, I had a major service done to it(atleast to my knowledge) 200 point inspection, complete tune-up all the recalls, afew Zillas, lowering of the suspension, miscellaneous powder coating etc...my car sat for several years in a garage in california before i bought it...maybe that helped things because i gave Rob the OK to fix anything and everything and it only cost me close to $5,000 keep in mind i requested some of the work that wasnt necessary....so I think 6-$7,000 is kinda high unless you need some big ticket items like fuel distributors etc..I have complete trust in Rob and and his service is excellent I live in NYC so my car was going there regardless, I cant say anything about DMC HOUSTON, because ive never had the pleasure of dealing with them as far as service on my car goes due to geographical limitations, but I dont think youll go wrong with either of the 2 shops I will say this though, there shouldnt be any questions on what Rob can or cant do, PJ Grady is as complete a Delorean repair shop as anyone else...you can contact me off the list if you want to know what was done on my car and for how much , i have a record of whats been done to the car somewhere.
