To give you an idea, I phoned Lexus to get a price for a pair of upper control arms, over £1,100. The pair from Rock were (and these weren't their cheapest) less than £100 including taxes and delivery for the pair. Regardless of what others might say, I knew when the parts arrived they were excellent quality, and three years on still fine. The parts not to buy from Rock are heavy items like brake discs because shipping goes by weight.
