MINI of Montgomery County

My 2003 Mini Cooper S was overheating and I took it in for service and this is the service estimate I got from Mini of Montgomery County: Overheating issue: - Water pump is leaking $1080 - The core support is also cracked and radiator is damaged and leaking $1740 - The tech is recommending the thermostat be replaced due to the vehicle overheating $260 - Also would be a good idea to do the coolant flush $240 Total: $3,320. They also came up with additional list of "recommended" fixes for $8,550. They had me so intimidated I thought I was going to have to buy a new car. When asked what they would give us in a trade-in, they offered $300 (yes, hundred--not thousand) --despite the fact that the blue book value on a trade-in for my car in fair condition is $5,185 ($6,435 for excellent) to give a frame of reference. I had replaced the water pump about 2 years and 2 months ago at Mini of Sterling and they refused to stand behind their work, saying that they warranty it to 2 years, that's it. Customer loyalty, years of taking my car there, and thousands of dollars later meant nothing. They wouldn't stand behind it. Although, Mini of Sterling did say that they would do the work for less than $2,700--meaning that Mini Of Montgomery County was charging over $600 more for the same work. I decided to get an estimate over the phone from a local, respected, foreign car mechanic in the area and his estimate for the same work was $1,570. I (thankfully) decided to take my car there for service. Almost immediately he told me that the problem didn't appear to be the water pump, radiator, or the thermostat. The problem was a hole in one of the hoses. He replaced the broken hose, another hose, pressure tested the system and my bill was $280. I've been driving the car for weeks with no issues. Not only would Mini of Montgomery County have screwed me out of over $3,000, but also their estimate didn't include replacing the hoses. So, either they would have tacked more money onto the bill later or I would have had the work done and it still wouldn't have fixed the problem. Either Mini of Montgomery County have incompetent mechanics or they are dishonest or some combination of the two. I will never take my car there again for service and I would advise anyone to steer clear of [non-permissible content removed]. PS - Mini emailed a customer satisfaction survey in which I expressed my displeasure and I requested a follow-up call from both the dealership and corporate. Mini corporate called and listened to my complaints and made excuse after excuse for the dealership, even going so far as to say "well, we stand behind our dealerships." Translation: They made the phone call because they had to, but they weren't going to do anything for me and if they lose me as a customer so be it. The person I spoke to didn't seem to care at all. Despite requesting that they contact me, Mini of Montgomery County didn't bother to call.
