Why Hayes drivers choose Onyx over a main dealer
Hayes locals tell us they came for the price and stayed for the honesty. No upselling, no surprises on the bill, no patronising service advisor.
- Main-dealer diagnostics. Manufacturer-level diagnostic software in the bay for BMW, Audi, VW, Mercedes, Ford and Vauxhall. Ferrari and Aston Martin get the same attention as a Fiesta.
- Payment Assist. First payment at booking, then 5 more monthly payments, 6 in total, interest-free. Up to £3,000, no setup fees.
- Same-day slots most days. Ring before 11am and we'll usually fit you in.
- WhatsApp before we touch anything extra. Photos of what we've found, the price, and you say yes or no.
- Service book stamped. OE-spec parts, warranty kept, no main-dealer markup.
