I have been a customer of Lexus Chester since 2004, through IS200, IS 300 Sportcross, RX400, ISC250, CT200 and IS300h. The dealership is far and away the best of the many I have encountered in over 45 years of motoring and I would include all the staff as none of them are anything less than friendly, enthusiastic & efficient and all go out of their way to look after us.
Yes, I've had to complain once or twice over the 12 years but the response has always been immediate and entirely satisfactory. I can quote many examples of their outstanding service, like the first time I took my IS200 ( bought second hand) for a routine service. When I collected it I was informed that they had observed corrosion on the alloy wheels and had replaced them all under warranty. I had noticed only some minor black stains on a couple of the wheels but had not thought to report it. A week later I was astonished when I opened the boot and discovered that they had also replaced the (used) spare wheel as well!
I would buy elsewhere if the standard isn't maintained but I see no signs of this at all.
