Brake repair service near Acton, IN

I called after being recommended from a work associate to have him work on my BMW. It took him a week to diagnose the problem (broke the timing chain and bent the valves). After this he says he has to eemove the head and send it off to be machined. It took him another week of only showing up part time to get the head off and get it to Schmidt automotive on the east side of Indy (which is an who ended up repairing Sparks mistakes). Once the head got back it took about a week and a half for him to get it back on my car. I got a call while at work that my car was finished so as soon as I got home I hopped into it and started it up and it sounded funny, put it in gear and it stalls time and time again. I call Sparks and tell him what's going on and he blames it on me! Says I must have broke it again pulling out of a parking space!! I tell him he has a warranty and he refuses to honor any of the warranty!!!! He then curses at me over and over telling me that I messed it up. I gave him a day and called back to see what he planned on doing to fix this and he just curses at me again! I called Schmidt to come pick the car up and lete know what's wrong and how much it's going to cost to fix it... Turns out that Sparks is an idiot and installed the head with a the valves open and my #6 cylinder at TDC!!!!! He just torqued the head on and forced it on damaging both the piston and re-bending my brand new valves! I called him again with the report from Schmidt telling him that the mechanics agreed that the only way this could have possibly happened was from improper installation... Sparks cursed at me again and refused to do anything about it. Stay away from this guy at all cost! I ended up paying out for the repair twice costing over $4k. USE A REPUTABLE MECHANIC!!!
