☀️❄️ Summer is here, and there’s nothing worse than a warm car on a hot day!

We’re excited to announce that we now offer A/C Regas here at Onyx! 🚗💨

In just the last week, we’ve already completed 20+ vehicle regas services and helped 20 happy customers get their air conditioning blowing ice cold again. 🧊

Whether your A/C isn’t as cold as it used to be or has stopped working properly, now is the perfect time to get it checked before the hottest days arrive.

📩 DM us today to book your A/C Regas and stay cool all summer long!

BMW M4 in for the full security package 🔒🔥

This beast came in for a Lock & Track tracker, Ghost Immobiliser, and deadlock installation to keep it protected from thieves.

While it was with us, we also carried out a Stage 1 remap — and the results were incredible. 🚀 The power gains on this M4 were seriously impressive, completely transforming the driving experience.

Now it’s making big power, fully secured, and ready to enjoy all summer long. ☀️🏁
