For buyers, the most immediate issue is not whether a vehicle is compliant, but how the market responds. Brands with efficient petrol, hybrid and electric models may have more flexibility on pricing and stock allocation. Models with higher emissions, particularly some larger SUVs and work-focused utes, could face tighter supply, pricing adjustments or changes in model mix over time.

That matters because a car loan is based on more than the sticker price. A cheaper vehicle with higher fuel use, insurance costs or weaker resale value may not be the best long-term choice. Conversely, a more efficient model may cost more upfront but reduce running costs across the ownership period. Before signing, buyers should compare total costs, model repayments under different rates and terms, and leave room for registration, insurance, servicing and charging or fuel expenses.

Small business owners should be especially alert. Many depend on utes, vans and SUVs for daily work, and vehicle choice is often driven by towing, payload and reliability rather than emissions alone. If popular work vehicles become more expensive or harder to source, commercial borrowers may need to plan purchases earlier, review lease versus loan structures, and check whether a newer efficient vehicle could support better whole-of-life value.

The used car market may also react. If new vehicle prices shift, near-new and used alternatives can become more attractive, particularly for buyers trying to manage borrowing limits. However, strong demand can also keep used prices elevated, so it remains important to inspect carefully, confirm service history and avoid stretching the loan term simply to make a higher purchase price feel affordable.

The practical takeaway is preparation. The emissions standard is another reason to look beyond monthly repayments and consider long-term affordability. Buyers who understand their budget, gather documents early and compare finance options before visiting a dealer are better placed to move quickly when the right vehicle appears, without accepting the first finance offer on the table.
