I went into Selecta Tyre (Kettering) they asked how much my Yokohoma's cost.......They guy said, oh we could have beat that.......
Offered me 2 x PE2's fitted, balanced for £150.
I didnt need them, drove away and 20 mins later noticed a nail in my tyre, went back - the manager quoted me £82 a corner for Toyo Proxies T1-S.
I said how I was offered the PE2's for £150 and he knocked the Toyo's down to £120 fitted as they dont hold PE2's in stock.
