Was this a dealership that provided this estimate to your friend? I took my Jeep to the stealership near me. I only took it there for the $17 oil change offer. They also provide an inspection, which is how they intend to to make the money.
They found repairs I needed for a total amount of $1400.
Transmission fluid change/service-$240
Differential fluid change/service-$250
There were a couple of other things they listed, but don't remember offhand what they were. Needless to say, I said no thanks. I took it to a trusted mechanic, $200 later I have everything squared away.
After this visit, I checked into this dealer. The dealer I went to has a horrible reputation, I checked their Better Business Bureau rating, they have a D. BBB said something like "use strong caution when dealing with this business".
Can you imagine a person who knows nothing about cars getting scared into something like that? It's sickening. Places like this should be shut down and the owners and people participating in this practice should be arrested.
