This has their "tyres for life" promotion and some details with "Purchase a used car from Sinclair Ford and we'll give you FREE tyres for the life of your car!*"
The asterisk conditions are "* Tyres for life program excludes 4x4 vehicles with 18 inch wheels and larger. Terms and conditions apply for program qualification, please contact Sinclair Ford Used cars for more details"
Be interesting to see the full terms and conditions as I'd expect there to be a heap of outs for them.
