No, it's not a low growl, it's definitely the brakes grabbing on huge rear off side.
To be honest Neil from Surrey, I wanted to buy a lovely big Skoda I found on autotrader but it was in Shakespeare country, a good three hours away. I did look at an rx with full service history in Bury (as in the world famous market, and black puddings) but it looked as if the previous owner had been off roading with a car full of small children - it was knackered and had suffered five owners. The one I did buy had a mere three owners, and in suspect one was a dealer.
I will be taking the car to the dealer next week - the dealer's exact words were "do not worry, it is my duty to put it right." I think I will let him 'fix' it and then take it to my local trustworthy mechanic who will tell me the truth!
I do hope it turns out all right, it is a lovely car and the best quality I could afford, I think.
The truth is, I put plushness of interior before all else. This rx was the only car within my price range that came close to the luxury interior of the Skoda I was tempted by.
