Cat premiums are a stretch for the value received as compared to other market alternatives – how can I justify paying more?
Caterpillar’s cost per hour is less than other market alternatives even though the initial purchase price is higher. The cost per hour calculation is necessary is understanding overall product value. Cat’s components are reusable/rebuildable – bushings, track rollers and idlers. With the purchase of Cat parts comes the unmatched commitment and expert support from Caterpillar and its dealers. Undercarriage Assurance guarantees against leakage and breakage for an extended time period.
Isn’t Undercarriage Assurance comparable to what many competitors offer?
Cat Undercarriage Assurance is the best in the industry. The Cat dealer strives to inspect undercarriage at the end of the assurance period. Competitors frequently do not honor their stated coverage to the customer.
