5 stars to Euro Car Doctor. I had received a diagnosis from the repair company I've been using since I moved further south in the OC (use to live in Irvine) that my old 2004 330ci convertible probably had a cracked head gasket and repairs that "might" fix it could be upwards of $5k. I use to go to go to "BMW Coast Motor Works" which was Euro Car Doctor's former name, and thought I'd get a 2nd opinion. Thankfully I did, as they have some more techie diagnosis tools, and found that I didn't have any cracks in my head gaskets, but most probably had air in my radiator line the was causing my car to overheat intermittently. They performed the fix for this issue, and that solved the problem!! While in the shop they found a few other items I needed repairs on, and I'm working my way through those as the budget allows. Having this Convertible isn't the cheapest car to keep, but it's a classic that I still enjoy driving and it's a 2nd car so I can take the time to work on it's needed repairs. I appreciated the excellent communication provided, and their text-based quote system provides all the cost and explanations needed to help understand what items need repairs.
