Good luck. There's a lot of money in a tractor unit-so they tend to get rebuilt. The body-on-frame construction helps make rebuilding economical too.

Bit of a closed shop with tractors. Manufacturers keen to keep them off the second hand market as it adversely affects residuals and reduces demand for new. Market often controlled by guaranteed buy backs usually by the manufacturer - whether purchased by the operator or a finance company.

From my limited experience there seem to be 'salvage agents' that insurance/accident management companies use.

Rather than damaged units, you might want to try smaller or family run hire companies that run tractors older than the finance owned nationals - to 7 years + in some cases - to buy at end of economic life (as a hire unit). Massive demand for hire from Sep to end of the year, so Jan/Feb the best time for this.
