I know nothing of the car or its condition, equally I know nothing about the dealer.
The Dealer said. . ."Total bill to me of £3260.98. . . including 4 new Brigestone tyres". . . .
A check on the Lings website will show that as a HUK parts, for H870ARR, a set of 4 specified tyres would set you back a total of £5,446.96. At £1,221-90 each for the fronts and £1,501.58 for each of the rears those tyres must be very special and/or the dealer discount very, very significant.
Notwithstanding an introduction to HUK parts pricing, welcome and enjoy the car.
