My tire was leaking air. I was told it was not repairable because there was a nail too close to the sidewall. In addition it was recommended that I replace all the tires because they were showing less than 4/32" on the treads. The car has run flat tires but was told that I could replace them with run flats or regular tires. I was quoted prices for both types. The car is still under warranty and so before making a decision I took it to the dealership where I bought it for a "second opinion". According to the dealership, all the tires are fine and the problem was a leaking tire pressure sensor which they replaced. Wow...........
On another occasion (with my previous car) I was quoted prices for lots of things that "needed to be fixed or replaced". The car was 10 years old and before I dumped a ton of money into it, I took it to the dealership and had them determine its "road worthiness". According to them, absolutely nothing was wrong with the car.
More conveniently located than the dealership, but unfortunately, I'm done with Conrads :-(
