Inspection, advice & certification pricing is on a case by case basis. Due to the complexity and variety of vehicle modifications, quotes cannot be given in most cases, and I’m unable to quote fixed prices for any certification. Despite the myriad variables involved in quoting certification or modification work, you can count on Leeder Automotive Services to provide fair, reasonable and competitive pricing for its services.

Time & cost

The time and cost of our work can be affected by access to information necessary to the completion of work. By providing information and documents we request in a timely manner, we can hasten the return time of your vehicle inspection, and offer lower costs in service time. If we need more information to complete your inspection, it’s in your best interest to be as prompt as possible.
